How to Prepare for JEE Main Online 2019

JEE Main, the Joint Entrance Examination, is a common testing platform for all engineering aspirants. This exam opens gateways to NITs, IIITs, and CFTIs all over India.

Until 2018, JEE Main was conducted by CBSE. However, from now on it will be conducted by the National Testing Agency (NTA). The NTA has introduced a new pattern of examination — the examination will now be held online. So here is all you need to know about the new JEE online pattern and its advantages. I’ll also talk about some simple techniques to ace JEE Main online.

The New JEE Online Pattern

The NTA has decided to make JEE Main 2019 completely online. Until 2018, students had the option of choosing between online and offline mode of examination. But now, there is no such option. The exam will be conducted in a completely computerized mode.

Two Papers

There will be two papers — paper I and paper II.

Paper I is comprised of three sections — physics, chemistry, and mathematics. Each section has 30 questions. Each question carries a positive marking of four marks and negative marking of one mark. Paper I is completely online.

Paper II is also comprised of three sections — Mathematics, Aptitude, and Drawing test. The mathematics section consists of 30 questions. Each question carries a positive marking of four marks and negative marking of one mark. The Aptitude section consists of 50 questions. In this section the student is awarded four marks for a correct answer. One mark is deducted for a wrong answer. You get zero marks for an unanswered question. The Drawing section consists of only 2 questions for a potential total of 70 marks. Evaluation in the drawing section is based on the student’s drawing skills. Section one and two are conducted in online mode, whereas the drawing test is pen-and-paper.

Students aspiring for B.E./B.tech are supposed to give paper I. Those going for Architecture can give paper II.

Another Major Change

There is another major change that the NTA introduced this year. Now, the exam is going to take place twice a year– in January and April. Your best score of the two will be considered for counseling. That’s good news! You now have two chances to prove your preparation and showcase your skills. Earlier, the exam was held only once a year and that left little room for inefficiencies. But now you get another chance to prove yourself. This can be a lifesaver if something goes wrong the first time around!

New Patter Means New Practice Method

The new pattern calls for a change in the conventional method of practice. Do you want to:

  • rise above your competitors
  • fully apply your knowledge, and
  • take full advantage of the new JEE online pattern?

If so, then you need to slightly modify the way you attempt the exam.

Advantages of the Online Pattern Over the Offline Pattern

Considering the current generation, no doubt, the JEE online pattern is the best mode of examination. It makes the process less time-consuming, more efficient, faster, less costly, and eliminates human error to a large extent. Also, this ensures a uniform pattern of conducting the exam throughout the country with no bias.

Now let’s talk about some of the major advantages that this new, online exam offers.

You Can Change an Already Marked Answer

In an OMR sheet, once you darken a bubble, that’s the final answer. But then sometimes, you realize that the answer you marked was not the same as you calculated. By mistake, you marked the wrong answer. What do you do then?

There is no solution to this and you end up regretting your carelessness. The online mode eliminates this problem because you can change your answer as many times as you want! Once you mark your final answer, you can press the ‘save and continue’ button to save your response and move ahead to the next question. But note that even after saving your response, you can change it later and save a new response.

Saves Time and Effort

We all know how much time and precision it takes to darken a bubble in the OMR sheet correctly. That is why our teachers often told us to keep 15 minutes extra in hand just for marking answers on the OMR sheet. However, the JEE online pattern has eliminated the need for this type of system. You can record your response by simply clicking on the desired option and pressing the save button. This saves you the hassle of darkening bubbles, and also leaves little room for mistakes.

Helps Avoid Confusion

Many times, when you sit to darken all the bubbles in one go, it so happens that you darken the wrong bubble or you get the order wrong. When you finally realize this, you have already come a long way and marked a lot of questions incorrectly.

So, now you have two choices. First, you can get a new OMR sheet and start over. Or if that is not possible, you have to just sit there and hope for the best to happen. But the online system has made it so much easier now! There is no scope for such mistakes because only one question is displayed on the screen at a time, and you are supposed to mark the answer when you solve the question. Again, great news.

Properly Organized

On the pen-and-paper exam questions were sometimes written in multiple languages. This caused some students to get confused, resulting in wrong answers. On the contrary, the online mode only displays one question at a time, and in only one language. You chose your language beforehand, so the paper is only presented in that particular language. This completely eliminates any related confusion.

Questions’ Palette

The questions’ palette is the most useful tool in the JEE main online pattern of exam. The question palette on the side of the screen lists the question numbers, with their respective status indicated against them. For example, let’s say you are on question no. 2 in the physics section. You have attempted question no. 1 and saved your response, so it will show a green mark against Q1. Similarly, there are other symbols for indicating a questions’ status. The symbols to be used in JEE Main online 2019 are shown in the mock tests at the National Testing Agency’s (NTA) website.

Another advantage of the questions’ palette is that you can access any question with just a click. This saves you the hassle of going through the pages, back-and-forth to search for the desired question. Also, you can mark a question for review and come back to it later. The question palette will clearly indicate which question you have marked for review, and you can easily select that one. The questions’ palette keeps all of this information well organized. It makes everything readable and easy to access, unlike the mess that was created in a pen-paper test.

Rough Work Made Easier

Usually, in a pen-paper test, rough space is very limited and randomly distributed. Very little space for rough work is provided on the same page as the question. And worse, only one whole page for rough work is attached at the end of the exam. To do calculations, you have to constantly turn pages and search for the information in the question.

This process becomes messy, time-consuming, frustrating, and exhausting. But in the online mode you are given separate sheets for rough work. So you have the advantage of looking at the question on the screen right in front of you while you solve the question. This helps you avoid mistakes, and saves a lot of effort.

Tips to Ace the Online Pattern of Exam

With all the advantages listed above, we are sure that you are super-excited to try your hands on the new pattern. But it is important that you understand the pattern well in order to make the most of it. Here are some easy tips and tricks to ace the new JEE main online pattern.

Practice in the New Mode

Yes, the new pattern makes it much easier to attempt the JEE Main. The interface is user-friendly, and we can all celebrate that! But you still have to practice well with the new pattern in order to get used to it.

Practice as much as you can to get familiar with the tools and the interface. This practice will make you more comfortable during the exam, and help you navigate smoothly through the questions. Practice will keep you from panicking about the controls during the exam. So try different ways of attempting the paper. Experiment during practice to find the best technique for you, and then apply it in the actual exam.

Practice Centers

The NTA has set up practice centers for JEE main 2019 online mock tests. You can register in any of the centers near you. Then go there to practice from time to time to get a feel of the new pattern. Coaching institutes have also started conducting their practice tests and internal tests in the online mode to give their students enough practice in the new pattern.

Be Careful

It is very important that you keep your calm in an online exam. You simply don’t have time to panic. One wrong button can terminate the exam for you or can cause some major error. So always read the instructions carefully and understand them well. Click on each and every button very carefully. Don’t forget to save your answer by pressing the ‘save and continue’ button.

If you do not press the ‘save and continue’ button after marking your answer and directly jump to the next question, then that question will be treated as unattempted. If time is over and you fail to press the submit button, only your saved answers will be counted. Unfortunately, the ones left unsaved will not be evaluated. Be careful not to click the ‘Submit’ button without completing your paper. Before submitting, make sure everything is in place. Take a look at the questions palette. See if there are more questions you can solve or if you want to review some of your answers once again.

Time Management and How to Attempt Questions

It is very important to manage your time wisely. We’ve always talked about how important that is during the JEE. But it is especially true now that the exam is online. You see, with the online mode the test is terminated automatically the minute time is up. You no longer have the option of asking the invigilator for extra time. So, manage your three hours wisely and divide your time according to the respective sections.

Instructions Are Important

First of all, read all the instructions carefully. You can take your time as there is no countdown in that. However, five to ten minutes should be enough to go through the instructions and get familiar with all the tools and buttons used in the exam.

Start the Clock Please

When the first question appears–and the clock starts. Don’t panic when you see the clock. Just take a deep breath and accept the fact that the clock is going to be there ticking away as you proceed through the exam. That can derail you if you let it. Don’t keep looking at the clock as it will only make nervous. Look at the clock only when you feel it’s necessary to make sure you are on pace. Don’t let the clock distract or bother you while you are solving a question because this will hamper your thinking process and keep you from concentrating well.

Time Management: Use Your Questions’ Palette

Now, look at the questions’ palette and see for yourself which section you would like to attempt first. Click on that and start with the first question. Note that in an online exam, questions are displayed one by one. So it is not a very good idea to click the ‘next’ button several times to see through all the questions once. This can be quite exhausting and time-consuming.

Start Fresh

What we recommend is to start solving the first question with a fresh mind. Don’t spend too much time and energy on any particular question. Whenever you get stuck, leave that question, mark it for review later, and move on to the next question. Don’t get disheartened by the questions you can’t solve; instead feel confident about the ones you could solve. Confidence is the major factor that determines performance in any exam. So build up your confidence by solving all the questions you can, and by focusing on questions you find solvable.

As I said earlier, don’t constantly look at the clock. But do look at it from time to time. If you realize that you’re going to exceed the time you allotted for any particular section, look through the remaining questions quickly and solve the ones that you can. Then hop on to the next section.

Review Answers

When you are done with all the sections, come back to the questions you marked for review. First try to solve the ones that you find the easiest, and save the most difficult for the end. In an exam like JEE Main where all the questions carry equal marks, your aim should be to solve a maximum number of questions correctly and not get stuck over the difficult ones.

Once you are through with your paper and sure of your answers, click the ‘submit’ button. If you don’t click the submit button, the test will automatically end as soon as the countdown reaches zero and all your saved responses will be counted. Just make sure that all the answers you marked have been saved. You can do this by looking at the questions’ palette. Just make sure it shows the status of all the questions from unattempted to attempted.

Read the Instructions Carefully

It is highly recommended that you read and understand all the instructions carefully before beginning the exam because you might not be able to refer to them again and again once the exam begins.

Rough Work

Rough work is a crucial part of any competitive exam. The way you manage your limited rough space can make a lot of difference in the exam. In the JEE main online exam, rough sheets are provided separately for working and calculations. You must wisely use the rough space. Your rough work should not be so messy that you can’t refer to it again. In fact, you need to keep it neat so that when you review it you can figure out what you have written! This means you don’t have to start all over again.

Number Your Questions

So first, put the question number on the rough sheet when you start solving any question. After you’re done, draw a box around the calculations for that particular question. This will prevent two or more questions from getting mixed. Also, we recommend that you quickly copy major information from the question onto your rough sheet. This is helpful because you don’t have to keep looking back at the screen to refer to the question.

The JEE Main is an exam with questions carefully designed to test your problem-solving skills under pressure and time constraints. Most of the questions are not very lengthy or complex. And the paper contains a variety of questions ranging from easy to difficult. The most important skill in JEE main online is to choose the solvable questions so that you can answer the maximum number of questions correctly in the given amount of time. We hope that you have put in your best in preparing for JEE Main 2019 online. Knowing and understanding the changed pattern will give you a better grip on the exam.
All the best!

Solutions

Question #1

First, draw the FBD.

Find the value of limiting friction by multiplying coefficient of friction with the normal reaction. Then find out the downward acceleration, a along the incline. This is the same acceleration with which you have to push the block upwards. When the block moves upwards, a friction force acts downwards along the incline, opposite to the applied force F. By using Ff = ma, find out F.

Question #2

First, find angular velocity of the coin using revolutions per second. Then find out the centrifugal force acting on the coin because of rotation. Equate frictional force to this centrifugal force.

Question #3

Using the details mentioned about the cube having the side of 25 cm, find out its shear modulus. Since the other cube is made of the same material, it will have the same shear modulus as that of the first cube. Now, with this information and the other information given about the second cube in the question, find out the displacement in that case.

Question #4

CO   +   Cl2   ⇋   COCl2
 6          4                    t = 0
(6 – x)  (4 – x)    x      At equilibrium

3 moles of CO left, that means, 6 – x = 3, —> x = 3

Now find out the value of Kc using this value of x in the expression for Kc.

Question #5

Take a general quadratic equation
f(x) = ax^2 + bx + c
Using f(1) + f(2) = 0 and f(–1) = 0 find c/a.
Product of roots = (–1)(other root) = c/a

Question #6

Let angle of elevation of the top of T2 from top of T1 be. Then the angle of depression of the bottom of T2 from the top of T1 = 2 θ
Let width of road = b
Tan θ = 40/b
Tan θ 2 = 120/b
Now solve for b

Preparing for the changing exam pattern is important. It will definitely lower your stress level during the exam! As you can imagine, this is very important if you want to perform to your full potential in the JEE. Hope you find this post helpful. All the best for the exam!
