  • 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.

  • Phillip P. Carpenter, Ph.D.

    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.

  • 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.

What people are saying about Med-Pathway


  • The book has 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
  • 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 2016, and I am confident Pathway will help her succeed in her MCAT goals.
