Focus on experimental science and techniques as presented on the MCAT™ with detailed graphical annotations.
2021 Flipped MCAT workshops
Flipped classrooms are an active form of learning that are being adopted in medical schools. Dr. Carpenter is a pioneer in this style of education as described in his recent Medical Education article (download now). In the med-pathway flipped MCAT classes, students watch content review videos prior to the class. During the class, we work through passages testing topics on the MCAT that are designed to improve cognitive skills with respect to interpreting experimental data. Just like the MCAT.
Learn cutting edge science topics like RNA coronaviruses and their application to clinical medicine.
Just like the MCAT™, Med-Pathway applies foundational principles of science to clinical medicine. Learn how a stenotic artery requires greater pressure to achieve the same flow rate as a normal artery.
Med-Pathway has FREE subject content review in multiple areas of biochemistry: proline has no amide H bond and cannot incorporate into an alpha helix.
Learn how to apply laboratory techniques to clinical conditions such as sickle cell anemia.

1. An optional tutorial session to familiarize yourself with the features available on the test (i.e. strike out, highlighting, and flagging questions).
2. Both normal and accommodation timing is available as is pausing the exam.
3. Any breaks in between exams are set by the test taker.
4. The "Section Review "feature can be accessed at anytime during the exam and shows unanswered and flagged questions and provides a method to submit the questions and for moving to the next section.
5. Detailed annotations (Review) are available through the Results Report after the exam has been submitted for scoring.
Here’s what people have been saying about Med-Pathway.
Dear Dr. Carpenter,
I hope this email finds you in good health. In August, we connected on a phone conversation and I informed you I was having trouble raising my MCAT score from the 500-506 range. After two months of dedicated study, I scored a 509 on FL1, 514 on FL2 and 519 on FL3. Today, I received my score on the MCAT, a 516 which is a 93rd percentile score. Although I did not meet my 528 goal set for myself in the beginning of June, this score has cracked the door open to, hopefully, a successful MD/PhD campaign in the 2021 application cycle.
I would like to thank you for your words during our conversation; they played an immense role in allowing me to set aside fear and replace it with the confidence needed to climb the score ladder.

After coming across pathway, it was only about 50 dollars, so we went ahead and bought it. The passages were definitely challenging, but in a way that forces you to think and come to your own conclusions given experimental data, and if you really get stuck the problem solutions are detailed, well written, and coherent. Many of the passages read as research articles and after a brief introduction to the material, ask you to analyze and comprehend experimental data, which I found refreshing since much of the other content my girlfriend and I have found was weak in this area. My girlfriend plans on taking her test in January, and I am confident Pathway will help her succeed in her MCAT™ goals.
- Jeff M.
Hello Phil, it’s Jessica Kern, I wanted to sincerely thank you for your MCAT prep exams. It was a really great resource for me during my studies. I got my results back yesterday and scored a 521, so clearly your tips are spot on. With that and my letters of rec all taken care of, my final step is writing my personal statement and activities list. I’ll be sure to keep you posted on the journey!
- Jessica Kern
The exams have really helped in the sense that it is much more difficult and requires more critical thinking to answer correctly. Which I believe is wonderful for the MCAT™ because you must be able to analyze the questions and passages to succeed, besides the content knowledge required. I especially love the detailed annotations after each passage so I may look over what I did correctly or incorrectly for future passages. It has been a great resource to have and I hope I have time to look over the practice exam before my MCAT™.
- Anthony Soto
Here are my comments on the med-pathway passages. Biological sciences-good content wise, nice focus on Biochem concepts and questions, really good answers. Physical sciences-good combination of biochem/physics/chem, good questions and explanations. Passages are dead on with MCAT, maybe more difficult. CARS-passages longer than actual test and easier to follow, good questions and explanations. Psychological-challenging passages, great questions and explanations, pretty similar to actual exam.

We set out to create the best MCAT™ resources available.
Our mission is to provide advanced passages and testing materials that stress scientific scenarios from the three major science-driven sections of the MCAT™ exam, as well as to provide thought-provoking passages to increase your critical reasoning skills.
I have been actively involved in medical school teaching for over 15 years and have received many awards. I have also taught MCAT™ classes as well. Combined with my research experience, I have a strong feel for what is required to succeed on the MCAT™ and how this transitions into medical school.
Dr. Carpenter has developed flipped classroom teaching pedagogies that have been shown to be highly effective in medical education as shown in this recent publication. Flipped classrooms are an active learning tool that improves learning and critical thinking skills. See the free resource section on this site for the publication: Carpenter. P.B., Poliak, A., Wang, L., Ownby, A.R., and Hsieh, P (2020) Improved Performance In and Preference for Using Think-Pair-Share in a Flipped Classroom. Med Educ: 54:449-450.
I have been teaching medical students since 1998, and have won awards from my school for my teaching efforts. I teach courses in the psychopharmacology, neuroscience, and the behavioral sciences. I am also an active researcher with funding from NIH since 1998 and more than 120 publications. I bring this skill and experience in biomedical training and research to bear on the development and explanation of content material on the MCAT™, particularly in the behavioral and neural sciences.
I have taught for over a decade in classes that have included medical students, psychology graduate students, and psychology undergraduates. I am expert in behavioral sciences and conduct research studying substance use disorders and impulsivity. Both my teaching and ongoing research experience allow me to provide content reflecting broad foundational material in addition to topics based on recently discovered findings in the field.
I have been involved in MCAT test preparation for over 14 years and have taught medical students for nearly a decade. During the daytime, I run a federally funded lab and do research in the field of RNA Biology. This background enables me to develop data-based content that is cutting edge.
