Mahmoud

“After spending 4K+ on a MCAT testing company on my first attempt, I retook the MCAT with Andrew. The website/system that Andrew offers is the utopia of MCAT preparation. Not only does it prepare you for the MCAT but also, changes your lifestyle and how one should properly approach the MCAT. During the diagnostics & taking FLs, my score changed from a 495 to a 510 and I witnessed a 7 point increase on the real deal. With the great great great great FLASHCARDS that I was able to use anywhere, I got the MCAT score I wanted. HIGHLY RECOMMEND. Thank you Andrew for all your work.”

Lemuel

“One of the things that really stood out to me was Andrew’s emphasis on high quality note cards as well as his program’s affordability compared to other companies. On test day, I got a 514 with a perfect score in Behavioral Sciences. It’s been my experience that using note cards is the best study method for the MCAT, as most of the questions are looking for you to apply small pieces of memorized information to different situations. I definitely felt over-prepared on test day. You can’t find a more concise yet comprehensive set of note cards for this massive test than Andrew and his materials!

Ryan

“As a 30 year-old non-traditional applicant, I had to find every topic covered on the MCAT and then re-teach it to myself. Andrew’s course was a great way to do that. The main course is free, but I did purchase the Practice Question Bank and a few other courses (Math, 100 Equations, Amino Acids). All of the information I learned was invaluable to my success on the exam and admittance into medical school. I highly recommend the use of this resource. Everything is straightforward and there were no issues with any unnecessary charges.”

Frequently Asked Questions

Which plan is right for me?

If you are not sure which plan is right for you, simply request a free consultation with Andrew and he will point you in the right direction. He’s worked with hundreds of students and knows what you’ll need to achieve your goal in your unique situation.

If I am not currently using the MCAT Self Prep eCourse, will these practice questions help me?

Yes! The Flashcards are organized in the same way as our online eCourse, but they can be used in conjunction with any other study tool. They cover every single concept taught by Khan Academy as well as several content review books, so if you are looking for a way to quickly test yourself on every single MCAT concept, you will love our practice question bank.

Why should I upgrade from the Free Forever to the Advanced Pro Plan?

Although the Free Forever Plan and Basic Pro Plan provide you with the ability to try out 300 Flashcards (about 3 per lesson), and sample 120 mini-Quizzes (3 questions per quiz), the Advanced Pro Plan will provide you with full access to all 5,000+ flashcards and 2,500+ AAMC-style practice questions integrated into each lesson. Students love using these practice questions to double-check their understanding of what they learned during each content module, do a rapid review of every single MCAT concept, or save them time from needing to make thousands of their own flashcards. Our Practice Question Bank is our most popular resource.

If I start with the Basic or Advanced Pro Plan first, will you reimburse me when I upgrade to the Deluxe Pro Plan later?

Yes! We are big believers in “try before you buy.” As soon as you sign up for either the Basic or the Advanced Pro Plans, we will provide you with a discount for the higher-tier plans equal to the value of your purchase. For instance, if you start with the Basic Pro for $19.99, you will automatically receive a $19.99 credit towards your purchase of the Advanced or Deluxe Pro Plans. If you start with the Advanced Pro Plan for $199.99, you will get a $199.99 credit towards your purchase of the Deluxe Pro Plan.

Who created these flashcards and practice questions?

Our Founder and Head Tutor, Andrew George wrote most of these flashcards and each one has been edited at least twice by one of our Elite Tutors.

When will my access expire?

All our products are a one-time payment for lifetime access. 🙂 While other test prep companies have strict expiration dates for all of their plans and programs, we do not believe that is fair to you. You deserve to be able to access what you purchased until you have taken the MCAT and are satisfied with your score.

Can I defer my payment or pay in increments over time?

Yes! Simply select affirm pay over time at checkout to customize your payment plan with affirm. In some cases, affirm can decline users from using their pay-over-time service. If this happens, you can shoot me a message, and we’ll get you set up with a personalized monthly payment plan that will suit your financial needs. If you have questions or need to make changes to your affirm payment plan, you can contact affirm here. For non-affirm, custom payment plans, contact us.

Can I share my account with a friend or relative?
We trust that you will not share our products with your friends, relatives, or even siblings. In return, we offer you our support and the lowest price out there. MCAT Self Prep is a family business, which provides a livelihood for those working hard to provide you with quality test prep. By offering students lifetime access to our pro plans, we run the risk that you will share your account with others, ruining our ability to make a living. Instead of having expiration dates for plans or implementing strict security protocols, we believe in having a relationship of trust with you. Please treat us with kindness and respect in return.

If you have a unique situation, have a lot of questions, or are looking for a confirmation that you are making the right purchase, you will likely benefit from consultation with our Head Tutor, Andrew George. He has worked one-on-one with hundreds of diverse students and will carefully consider your unique situation as he provides a careful recommendation and answers your questions.
