Hi premeds, I just took my MCAT on August 6 and I have some feedback regarding which test company to use. I have used Kaplan, Princeton Review, AND Next Step. I also tried to use 2007 Berkeley Review and EK 1001 verbal. Of course, the most important book to get is AAMC official book. 1) Kaplan -Online classroom (school year): PLEASE do not use their online classroom learning. This was a waste of my money and there was minimal content review. Obviously without solid content understanding, it is difficult to ace the MCAT. On the actual MCAT, knowing my content front and back saved me on very difficult passages. Do not underestimate the importance of knowing your content. Also, don't study for MCAT during school year. I took easy classes and still couldn't keep up. -Kaplan 7 review books: -CARS book is horrible. They try to teach you to take notes on what you read for each paragraph, which is a time sink. Don't take notes unless you have to. This is true for all MCAT passages. -Physics book is great - great emphasis on what is important, easy to understand. I would recommend. -Chemistry book is great too - although some chapters like thermodynamics is confusing. -Orgo book - it was fine until we started doing mechanisms, everything was confusing to me beyond carboxylic acids lol. Orgo has always been my weakest subject, not sure if it is me or the book, but I still didn't understand orgo at the end. Fortunately real MCAT orgo is not that hard. -Psychology book - absolutely necessary. It needs more sociology concepts though but you can look them up on internet. I compared the topics against what is inside AAMC official book. -Biology book - highly recommend. Some concepts are not explained in depth but you can easily learn them from your textbook. -Biochemistry book - best book out there. Absolutely necessary. Know your biochemistry!!! Otherwise you will fail biology on MCAT. -All: Each chapter has 15 free standing questions. They do not represent real MCAT questions so don't bother doing them. Spend your time doing passages. -Kaplan practice questions: -I consistently failed their questions until I came back after studying from Princeton Review. I didn't do too many questions from them because I started using Princeton Review questions instead. Many times in Kaplan questions, I had a WTF moment because they are so confusing in logic. 2) Princeton Review -In person classroom (summer): I love this class and I have met really great instructors. Part of the charm is that I hang out with other students everyday to struggle together, and this motivates me. I would highly recommend in person classroom because it is way less depressing than sitting in front of your computer. Highly recommend their class. -Their 6 review books: -CARS - their strategies are slightly better than Kaplan but they didn't work for me. There is really nothing you can do for CARS except keep practicing. My score went up when I started reading the Guardian newspaper everyday on the train. -Biology / Biochemistry - this book is much more detailed than Kaplan, especially in terms of DNA, genetics, physiology. Extremely poor review in biochemistry, but other sections are worth studying in depth. -Physics - horrible book. Do not buy. -Chemistry - I didn't use their book because I used their class review -Orgo - I didn't use their book because I used their class review. -Psychology - absolutely necessary. When combined with Kaplan psychology book, and AAMC content outline, you are 100% set for the test. -All: Each chapter has some free standing questions, and 1 practice passage. The passages might be too easy in my opinion. -Science workbook: this book is wayyyy too easy so don't bother unless you never learned a certain concept before. Skip around and do passages you are weak in. -CARS workbook: I never used this book -Princeton Review online practice questions: -Highly, highly recommend these questions. They are so much better than Kaplan questions because they are very hard and they have clear logic in them. At end of each class, we would get 5-10 passages to practice. These passages will make you cry at first but after a week or two, you will breeze through them. The physical sciences topics are much harder than necessary, but if you can handle these PR questions, you can probably score insanely high on actual MCAT. The only problem is that you need more biochemistry practice questions, so supplement this section with Kaplan questions. You can probably get away with doing less physics, less chemistry, less physiology questions. -Princeton Review practice exams: -I didn't do them because I ran out of time studying. Let us hope I scored well on my August MCAT ^_^ 3) Next Step -Their company only has 1 to 1 private tutor, which is very expensive. I didn't use it. -Next Step 8 books: -I used part of their psychology and biology content review book. I thought psychology was OK but not good enough on its own. Biology is too easy. Also, their physiology section lacks in graphs and pictures. Not recommended. -I used their CARS strategy book. Highly recommend this book because they tell you several strategies and make you do lots of hard philosophical passages. 4) Berkeley Review 2007 - don't bother with physics, chemistry, or orgo review because much of the content is taken out or became easier. I thought their biology review book is OK but probably outdated. I anticipate their new MCAT 2015 book is better. 5) EK 1001 verbal - passages are good practice, recommend this book. 6) AAMC book - this book has an outline of everything you need to know. Don't waste your time studying what is not on there. Also, it has some practice questions in there, which is useful for your actual MCAT. Must buy this book. 7) AAMC practice exam - biological section is too easy, and CARS section is ridiculously easy. Expect harder sections on actual MCAT. -Overall feedback: Combine Kaplan and Princeton Review books when you study. Some sections are better than others, so just use whichever one you feel helps you understand the concept. Open AAMC book so you have content outline. Use Princeton Review practice questions and Kaplan biochemistry practice questions. Don't worry if you think physics, chemistry, or orgo is too hard. On the actual MCAT they are not as hard as Princeton Review questions. Lastly, know your statistics and experiments. Kaplan physics book had good statistics review, but just know it in the contexts of interpreting an experiment. You should probably read some immunology and biochemistry signaling science papers. Feel free to ask me questions!
