MCAT Question of the Day

When you’re prepping for the Medical College Admission Test (MCAT), the regularity of your practice is just as important as the quality of your practice. It’s better to study for 30 minutes every day for two weeks than to cram for seven hours the night before the exam! With that in mind, Magoosh is delighted to share our MCAT question of the day.

This question of the day will update every day of the month. It rotates among all for MCAT sections, covering MCAT subjects in the following areas:

Biological and Biochemical Foundations of Living Systems
Chemical and Physical Foundations of Biological Systems
Psychological, Social, and Biological Foundations of Behavior
Critical Analysis and Reasoning Skills (CARS)

Plus, our MCAT question of the day uses the same question type you’ll see on test day: multiple-choice questions with four answer choices. Ready to give it a try? Your first MCAT Question of the Day is below!

MCAT Question of the Day

Chemical and Physical Foundations of Biological Systems

The critical angle for light traveling from a medium with a high index of refraction to one with a lower index of refraction is defined as the angle of incidence that would lead to total internal reflection. What is the critical angle for light flowing from a medium with an index of refraction of 1.8 to air (index of refraction = 1)?

33.7^o
26.7^o
58.1^o
62.1^o

See the answer!

Incorporating MCAT Question of the Day in Your Prep

The MCAT Question of the Day is a great way to sharpen your skills, get acquainted with section topics and question types, and generally learn the MCAT format. Ideally, you’ll be using far more than this single question each day to get ready for the MCAT. While the daily questions cover each topic area you’ll see on the actual MCAT, you still won’t see every single topic that could be tested.

In other words? Don’t put down those circulatory system flashcards just yet! It’s still key to brush up on your physics, biology, organic chemistry, biochemistry, and all of the other areas of physical sciences, behavioral sciences, and verbal reasoning that you’ll need for medical school!

As you’ll see in our MCAT study schedules, the best MCAT prep involves a few hours’ study every day over a period of months (or weeks, if you’re pressed for time). The best prep includes four components

Lessons/self-study content
Practice questions
Full-length practice tests
At least some rest time each week

Come back to this question at the beginning or end of your study session each day to put your new skills and knowledge to the test! As you do, it’s a great idea to keep a notebook to mark down what the question tested, what section it was in, and whether you got it right or wrong. That way, you’ll be able to tweak your prep, adding a CARS passage here, swapping in more DNA questions there, depending on your needs.
