GMAT Diagnostic Test

Welcome to our GMAT Quiz page! Curious about where you would stack up compared to others taking the GMAT test? Take our Diagnostic GMAT exam here to get a sense of your current GMAT scores in Verbal and Quant. These free GMAT diagnostic tests are designed to gauge your skills on the GMAT exam. Answer explanations and a link to your recommended study plan will display at the end of each GMAT exam. (For a full list of our study plans, see the Magoosh GMAT Study Plan page.)

Take the Magoosh Diagnostic GMAT Tests

You should allow yourself 25 minutes for the Quant Diagnostic Test and 25 minutes for the Verbal Diagnostic Test. And remember, these tests measure your skills in all of the same question formats you’ll see on GMAT test day: Data Sufficiency, Problem Solving, Reading Comprehension, Critical Reasoning, and Sentence Correction. If you’d rather not take separate tests, take an all-in-one online GMAT practice test. Scroll down for more information on these GMAT question formats.

Or if you’re already familiar with these concepts, get started with your GMAT diagnostics now!

Format of the Magoosh GMAT Diagnostic Test

These short, free GMAT diagnostic tests are are best taken by students who already have at least beginner-level knowledge of the test. The quizzes assume that you are familiar with the basic question formats on the GMAT. For GMAT Quantitative, the Problem Solving questions are the same five-option multiple choice questions, similar to what you have seen on virtually every standardized test in your life. However, the Data Sufficiency questions are unique to the GMAT.

Similarly, on Verbal, Reading Comprehension questions are comparable to ones you’ve seen on many other standardized tests, but the Sentence Correction and Critical Reasoning questions might be a little different from what you have seen before.

If you are brand new to the GMAT, it’s probably a good idea to get familiar with the mechanics of the various question formats before you take these mock GMAT tests online. You can read about the format of GMAT test questions on this blog. And you can look at the GMAT “big picture” (question formats, topics, pacing, etc…) in Magoosh’s Hassle-Free Guide to the GMAT Test—or in the GMAT Official Guide from the Graduate Management Admission Council.

For both GMAT exam diagnostics, answer explanations are provided at the end. Pay close attention to these answer explanations, as they often contain tips and strategies that can be used to answer other similar questions. And on that note… scroll up to take the Diagnostic GMAT tests.

Diagnostic GMAT Exam Summary and Scores

Once you have taken each of the free online GMAT diagnostic tests, you will get an email with your score. Then you can look at your recommendations, based on your scores. The GMAT prep recommendations appear in the section immediately below.

By the way, don’t be discouraged if you found the mock GMAT tests hard: the GMAT test is supposed to be hard! Keep in mind that these are just diagnostic tests to measure where you are in your GMAT journey. No matter where you start, Magoosh can help you with your GMAT prep! You can choose between a live cohorted class with an instructor (which includes all our lessons and practice questions) or access to the self-study option by itself.

As you follow your recommended study plans, take notice of the types of questions that you get wrong. For example, are you stronger or weaker in Sentence Correction? And what is your accuracy like in Data Sufficiency versus Problem Solving? Pinpointing your strengths and weaknesses can help you craft the perfect approach to your studies!

Score Groups and Recommendations for the Magoosh GMAT Exam Diagnostic

What do the scores on the free online GMAT diagnostic tests mean? Read on to find out.

If you felt the need to take only one of these two mock online GMAT tests, you probably have a reasonably good sense of your skill level in the other area. So whether you are armed with just one diagnostic score or two, it should be easy enough to figure out which “bucket” best describes where you fit, based on your diagnostic GMAT scores.

If you feel that, for whatever reason, one section or another of the Magoosh GMAT Diagnostic Test did not accurately capture your skills, then feel free to explore the group that seems to represent you the best.  It’s always a tricky thing to balance the well-deserved confidence in one’s own strengths with a grounded sense of humility about what one still has to learn. Remember that few people have ever harmed themselves by being overly conscientious.  Trust your intuition to follow the recommendations that seem to best match your learning needs.

In each “bucket,” we recommend a different three-month plan. Three months is a good solid time that allows for ample improvement in your GMAT performance.  If you have more time, you might look at our six-month GMAT study plan. If you have less time, look at our one-month GMAT study plan, but if you can, incorporate some of the materials & recommendations from the relevant three-month plan. Below the individual plans, also see our general recommendations concerning the approach you should take to maximizing your scores in Quant (Data Sufficiency and Problem Solving) and Verbal (Sentence Correction, Reading Comprehension, and Critical Reasoning). (And for a full list of our study plans, including ones that are not among our standard recommendations, click this complete list of Magoosh GMAT study schedules.)

Many folks preparing for the GMAT test will fall into this group, including most people who are at the very beginning stages of their studying, and that’s perfectly fine. Yes, this is the “lowest” of the four groups in terms of Diagnostic GMAT scores, but this does NOT mean you are starting with any kind of disadvantage. In fact, an extremely intelligent student might choose to start with the advice in this section as a gesture of tremendous conscientiousness; from a pedagogical view point, this would be an admirable choice. I will emphasize, once again, that it is quite possible to start with these recommendations and get a score in the high 700’s on the GMAT test. Again, it all depends on your commitment to excellence.

1) I suggest this 3-month GMAT study plan. This study plan includes many different study materials that you should find helpful.

2) Use the GMAT Math Flashcards = drill these until you know them all. The concepts on these cards are a great help for both Problem Solving and Data Sufficiency!

3) Boost your skills with the GMAT Idiom Flashcards, drilling them until you’ve got them down. These cards are especially helpful in Sentence Correction. But they can also help boost Reading Comprehension skills, especially for non-native English speakers.

4) Your results suggest that you need to learn academic material, and not just go through practice sets. Many student who join Magoosh make the disastrous pedagogical mistake of binging on questions and ignoring lessons. Watch the lessons! And watch the answer explanations under the questions you miss; these are essentially mini-lessons!

With that in mind, you may not need to watch every single Magoosh GMAT video lesson. In the math lessons, the first modules in each set of lessons are elementary: if you can pass the GMAT quiz that follows a grouping of lessons, don’t sit through the whole module. At the end of most lessons, there’s a summary screen that outlines what the lesson covered: if you jump ahead to this screen, you will get a good idea about what was covered, and if it’s all elementary to you, you can skip that lesson.

That’s perfectly fine for the first couple sets of video lessons, but even by the time you get to Integer Properties, there are mathematic ideas whose importance not to be underestimated. At a certain point, you’ll probably want to watch all of your remaining lessons. It’s a balance: don’t waste time watching lesson after lesson of material you already understand inside-out, but again, lean toward conscientiousness if there’s a chance to understand something more deeply.

The Sentence Correction lessons account for more than 50% of all the Verbal lessons. The first lessons on Parts of Speech may seem basic, but it’s very important to master the terminology so you understand fully the later discussion.

5) Truly authentic GMAT test prep is very important no matter which score group you’re in, and nothing is more authentic than practice questions from the makers of the test, the Graduate Management Admission Council. So be sure to use the full-length free GMAT practice tests from the official GMAT exam website. If you need more prep, Magoosh students get 40% off of official GMAC practice exams here.

Click here for Group #2: Quant Score 1-6; Verbal Score 7-10

Many of the folks who land in this group are probably verbally-skilled native English speakers. It’s good that you have such a strong understanding of the Verbal concepts. What we need to work on is your math GMAT test scores! It may be that you were very good at math in other periods of your life and are just a little rusty now. It may be that you bid a bitter adieu to math sometime in the middle of high school, hoping you would never have to see this dreaded beast again, and now, after an absence of many years, this Grendel has stalked out of the infernal depths to confront you on the GMAT Quant! Either way, we can help you feel much better about your mathematical prospects on the GMAT test.

1) Here is Group 2’s best 3-month GMAT study plan. The resources in this study plan should meet your learning needs well.

2) Use the GMAT Math Flashcards = drill these until you know them all. And make sure you know how to apply these concepts to both Problem Solving and Data Sufficiency questions.

3) For a Magoosh student in this group, most of the Verbal lessons would probably be unnecessary. It may be good to watch the summary of some lessons, simply to make sure that you are familiar with all the points covered.

4) Of course, watch all the Magoosh math lesson videos. The recommended study plan has you go through the entire sequence, then start at the top, and watch them all again. If you watch any lesson and are aware you didn’t get all of it, watch it again right away.  Conscientiousness is more important than efficiency in learning!

5) If you are in this group, you should focus on GMAT math. You need to do math every single day, especially mental math. You need to work on developing number sense for the GMAT. People who love math get excited over all the patterns inherent in numbers: as one explores, one will learn more and more of these patterns. Make sure you watch the Magoosh lesson videos in the General Math Strategies module until you remember to practice all these habits every day.

6) Always include some practice materials from “the source”– the makers of the real GMAT exam (the Graduate Management Admission Council). Go to the official GMAT test website for some the full-length free GMAT practice tests from the official GMAT exam website. If you need more prep, Magoosh students get 40% off of official GMAC practice exams here.

Click here for Group #3: Quant Score 7-10; Verbal Score 1-6

A few of the people in this group will be techie American students who have always focused on math & science and who reflexively have avoided “things with words.” That said, I imagine the majority of folks in this group will be all the very intelligent folks for whom English is not a native language. If you are in this latter group, then congratulations on learning English well enough to read this blog article! You have come very far, and we can support you the rest of the way!

1) This is the recommended 3-month GMAT study plan. This study plan recommends several study resources that you will find helpful.

2) Use the GMAT Idiom Flashcards, drilling them until you have mastered all idioms.

3) If you are this advanced in math, you probably need to see very few math lessons. Take each GMAT quiz at the end of the Magoosh lesson modules, and if you continue to perform well on these, you are probably in good shape. If in the course of practice questions, you come across a math concept on which you are not 100% clear, go back to the related lesson to solidify that. Overall, this is probably not where you need to focus the bulk of your learning, but it’s still important to practice math enough to keep all your skills sharp and to see the range of variation in GMAT Quant problems. Maintain a healthy balance of Problem Solving and Data Sufficiency questions, keep your skills sharp in the most frequent GMAT Quant Concepts, and keep up the good work!

4) Watching all the Magoosh Verbal lessons is a must. This group’s study plan has you watch all of them, and then go back to the top and watch them all again.  Some of the other resources in that plan, such as the three MGMAT verbal books, will reinforce the same basic ideas.  On the one hand, everything you need is in the Magoosh lessons, and on the other hand, you’re able to learn ideas more deeply when you are taught them in two different ways. You should also ideall watch every video explanation to every Magoosh verbal question, regardless of whether you get the question right or wrong: always be pushing yourself to learn more deeply in every way!

5) As the person weak in math needs to practice mental math daily, the person who needs to boost her verbal performance needs to go through GMAT Reading practice daily. For someone whose native language is something other than English, I would recommend reading difficult sophisticated writings in English for at least an hour a day every single day: that’s a hour over and above any time you spend studying for the GMAT exam. Again, a hard habit to implement, but nothing about excellence is easy!

6) Don’t forget to take the most realistic full-length practice GMAT exams possible, including practice from the Graduate Management Admission Council, AKA the people who make the real GMAT. These full-length free GMAT practice tests are a good place to start. If you need more prep, Magoosh students get 40% off of official GMAC practice exams here.

Click here for Group #4: Quant Score 7-10; Verbal Score 7-10

If you are in this group, then congratulations! You already have shown tremendous progress toward impressive GMAT scores. Now, having said that, I will caution you: getting complacent is the best way to fall short of your potential. So many people get to this point and then lose a sense of urgency, and this is precisely why so few wind up with scores over 700. Even though your prospects are good, the worst thing you could do would be to take anything for granted. You still have to hunger for excellence. You still have to apply the habits of excellence assiduously.

1) Use this group’s recommended 3-month GMAT study plan. This study schedule includes many useful resources, targeted to your needs.

2) You probably know most of the content of both flashcard decks, but it would be particularly conscientious to run through each just to check.

3) It’s good to do high level reading as part of your preparation. Certainly, you should read enough to be highly conversant with the major issues in the business world, especially those issue in the sector you would like to enter.  Beyond this, read academic books or journals. Force yourself to read articles about which you have little expertise or spontaneous interest.

4) It’s always good to practice mental math, and if you have a facility with math, try to challenge yourself in this regard. For example, in the USA (and many other countries), license plates of privately owned cars tend to have three digit numbers on them: find the prime factorizations of those in your head. Practice squaring two digit numbers in your head. Add and subtract fractions in your head. By the time test day comes, there should be no mental math in which you are not already well practiced. This just might bring your GMAT Quant scores to even grater heights, both in Problem Solving and Data Sufficiency.

5) Challenge yourself to push to deeper and deeper levels of understanding of GMAT concepts. One of the best ways to do this is to put yourself into a situation in which you have to explain a problem to someone else. It is one level of understanding to known how to do a problem and be able to do it cold. It is a higher level if you can walk someone who is confused through the problem step by step, answering all her questions so the problem makes complete sense to them. You really have to understand something deeply to teach it, and this is the kind of deep understanding that can get you a top GMAT score. You can develop this “teacherly” understanding in a study group, or you can find opportunities on the GMAT forums. (These forums also provide answer explanations for practice questions!)

6) Don’t forget to seek out practice that closely matches the GMAT exam you’ll see on test day. Be sure to use materials made by the Graduate Management Admission Council that makes the real GMAT test, such as going online for these free GMAT practice tests from the official GMAT test website.If you need more prep, Magoosh students get 40% off of official GMAC practice exams here.

No matter which plan you opt for, these pacing tips can help manage your time when taking adaptive practice tests or the GMAT itself:

How to Use Each Diagnostic Test to Shape Your Study Plan

As you can see in the recommendations above, we have divided the possible diagnostic GMAT exam results into four “score groups” that include a recommended study plan and other tips and tricks.

Just as importantly, you should see this GMAT diagnostic tool as just a start to your studies, and not an absolute measure of your ability. In other words, just because you may do poorly in a given area (Data Sufficiency, Sentence Correction, Problem Solving, etc.) right now does not mean you’ll continue to do poorly.

So if you get a less than ideal score on a given diagnostic GMAT micro test, don’t panic! Instead, be aware that these two short mini-tests give a merely a tentative snapshot of where your skills might be for now. Real, in-depth practice is needed to fully measure your GMAT exam abilities. And of course, extending your GMAT exam practice well beyond each diagnostic also allows you to build and improve on all of your GMAT skills. And once you’ve started prepping, check out our GMAT Question of the Day for a new Verbal or Quant practice question for each day of the month!
