Option 2: Studying for the MCAT: read details below or jump to the Free Organic for the MCAT Course

Option 3: You need a full MCAT Prep program (not just organic) or a scholarship for free MCAT Prep
Option 4:
You need a study break. Check out the cool science podcast, BA in Science on Spotify (not affiliated with PG Solutions but a great listen!)

Chemistry from PG Solutions LLC

I'm Proton Guru (PG Solutions LLC) founder Rhett Smith. I got my chemistry training at the University of Toledo (B.S.), Case Western Reserve (Ph.D.) and the Massachusetts Institute of Technology (NIH Postdoctoral Fellow), and I have been a professor of organic chemistry at Clemson University since 2006.

I have created this free online organic chemistry class to increase accessibility to knowledge and to help everyone who is trying to adapt to our increased reliance on online learning. This is a complete organic chemistry class, with an online textbook, mini-quizzes after each lesson for self-assessment, traditional lecture videos, and a lot of teaching through solved problem videos. I hope that this online course will be as straightforward and helpful as possible.


​How to use this Site

Basically, you can just go to the Table of Contents and start the step-by-step process. From there, you can adapt the available material to your learning method. When you would like to study a topic, click on the link. Each link takes you to a Lesson page where you can study the topic. Each lesson page generally includes:


  • A short reading lesson, usually with a couple of solved example problems.

  • An online, timed mini-quiz of about five multiple choice questions so you can self-assess your understanding of the reading.

  • A lecture video to cover the high points of the reading 

  • A free response question video, with explained solutions, ranging from relatively straight-forward to quite challenging as the course goes on.

I will continue to add supplemental worksheets, practice problems, and more useful resources, especially as I (hopefully) get feedback from instructors and students!

Students and instructors: please email me if there are topics that you need to learn or want to see covered but that I don't currently cover on my site, so that I can continue to improve this course for everyone!

Full, Free Organic Chemistry

Affordable MCAT Preparation from MCAT Ladder (and a Scholarship Opportunity)

I have worked with the MCAT Ladder to developed a free MCAT Organic Chemistry Course. There is also a full MCAT Preparation Course designed similarly to my free MCAT Organic course. The MCAT Ladder was also developed to increase participation and opportunity in medical careers. The MCAT Ladder's motto is "Climb and Uplift!":

Ladder Philosophy - Climb

After each course up the ladder you will face comprehensive exams combining the knowledge from previous courses until you have slowly trained yourself to put it all together to face down the real MCAT exam!

This approach is more effective and less stressful than trying to frenetically learn from many different subject areas at one time.  

The combination of audio, video, visual, and textual learning materials in this course is designed for effective and efficient training for visual learners, auditory learners and reflective learners alike.

Ladder Philosophy - Uplift

For every MCAT Ladder course purchased we give a full scholarship to another student who may not otherwise be able to access an elite MCAT training program like the MCAT Ladder. We believe in making education and the medical profession accessible to everyone!

Affordable Preparation and Scholarships
The Full MCAT Preparation Bundle itself has nine courses (listed below) included in it only costs $500, so it is much more affordable than the other elite MCAT preparation programs run by max-profit corporations. The individual courses included in the program are:

MCAT Organic Chemistry

MCAT General Chemistry

MCAT Physics and Mathematics

MCAT Biology 1: Molecular Biology, Cell Biology and Genetics 

​​MCAT Biology 2: Anatomy and Physiology

MCAT Psychology and Sociology

MCAT Critical Analysis and Reasoning Skills

Courses can be purchased individually for $200 each or all nine can be purchased for $500, but full scholarships are also available. Scholarships are especially important for people whose families cannot afford an MCAT preparation program, for those underrepresented in the medical professions, and for first-generation college students. If you fit one of these categories, we encourage you to submit our easy scholarship application form. We are currently accepting applications due October 1, 2021 and award recipients will be notified on October 15. Access to the training program will then be available as soon as the recipient confirms acceptance of the award and completes required enrollment steps.
