What are the MCAT and GRE?

The MCAT (Medical College Admission Test) and GRE (Graduate Record Examinations) are both standardized tests for students pursuing higher education or, in other words, another degree on top of their bachelor’s.

If you’re applying to medical schools (both MD and DO), you need to take the MCAT. If you want to go to graduate school and get a Master’s Degree or PhD, you will most likely take the GRE. Of course, the MCAT and the GRE aren’t the only post-graduate entrance exams!  Check out Chris’s post for the differences between the GRE and GMAT (Graduate Management Admissions Test).

The table below looks at some of the differences and similarities of the MCAT vs GRE.

What’s the difference between how you study for the MCAT vs GRE?

One of the main differences between studying for the MCAT vs GRE is the amount of information you need to review for each test. Similar to the GRE, you also have to sharpen up your reading comprehension skills as part of your test prep. But for the MCAT, you’re also expected to review Biology, Chemistry, Organic Chemistry, Physics, Math, Sociology, Psychology, and Biochemistry. While you may have taken classes in the subjects I just mentioned, all of the material covered in those classes is probably not fresh in your mind.

Equally important is knowing how to take the MCAT. There test will throw a lot of information your way. Some of it will be useful in helping you solve a question. The rest of the information is extra and tests your ability to identify it as just that- a distraction. Think about it: doctors have a lot of test results that they look at when they’re diagnosing patients but only some of those results are crucial. So, the better they are at distinguishing useful from useless, the better they are at helping patients get better! In order to get an idea for how the MCAT tests you, we recommend that you study for at least 8 weeks. Be sure to check out Clemmonsdogpark’s online for more study help!

When you’re studying for the GRE, you review Math, Verbal (including vocabulary and reading comprehension), and how to write analytical essays. Unlike the MCAT, the exam usually provides you with the appropriate amount of information to solve the problem. There are definitely test-taking tips that will help you navigate the GRE, but most of your studying revolves around studying the topics tested within the Quantitative, Verbal, and Analytical Writing sections. Our GRE Study Plans accommodate students who wish to study for any length of time between one month, three months, or even six months!

Happy Studying! 🙂

    Wow! This is so helpful. Well written article! “Think about it: doctors have a lot of test results that they look at when they’re diagnosing patients but only some of those results are crucial.” This makes so much sense! Congrats on your medical school acceptance!

      Hi Srijamya,

      That is a big question that we are not prepared to tackle for you because it isn’t our area of expertise entirely. I highly recommend finding a guidance counselor or admissions professional who can give you better guidance. I also recommend researching entry requirements for neurosurgery programs you want to enter. This will give you a good starting list. Good luck!

    I plan to get my Doctorate in Osteopathic medicine and my PhD in psychology, can I just take the MCAT to get in to both programs?

      Hi Ike,

      That depends on the requirements of the universities where you intend to study. Typically, PhD Psychology programs ask for the GRE rather than the MCAT, while a Doctorate in Osteopathy is more likely to require the MCAT. That makes it less likely that you’ll be able to take one test for both. Also, although there is some chance you could find a Psychology Program and an Osteopathy program that both accept MCAT, there’s another possible complication: most schools don’t accept MCAT scores that are more than 3 years old. So unless you complete both degrees at the same time as a double major, your initial MCAT score will likely be expired by the time you start our second degree.
