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.

    Kind regards,
    - Gevick Safarians
  • 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.

  • Scott D. Lane, Ph.D.

    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.

  • Jin Yoon, Ph.D.

    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.

  • Eric J. Wagner, Ph.D.

    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.
