Chad has been making his instructional videos available online for over a decade and has been instructing science and pre-health students for close to two decades.  His videos and practice materials are widely recognized as being among the best online.  He is continuously revising his video lectures and practice materials to maximize student understanding and to provide the most efficient presentation of the material.

Chad’s videos are amazing. Chad has mastered the art of teaching complicated material in an understandable way. I hope he continues to offer his services at such an affordable price. His courses are worth every penny you will spend and more!! Thank you CHAD

Chad is by far the best teacher I’ve met for Chemistry. He takes complicated material and explains them in funny and simple ways so that they can be easily understood. In Chad’s Ultimate Organic Chemistry Review it’s nicely set up so that you can pick the area that you may be struggling with and watch awesome videos that clearly explain and teach the material better than any teacher I’ve ever had could. After the videos there are helpful quizzes for practice with explanations for why the correct answer is what it is. If you need help in just about any portion of Chemistry, there is no better choice than Chad.

This course has been a phenomenal help! The way you explain the concepts makes them easy to understand and remember because your goal is understanding. The many examples throughout the lecture helps solidify the concepts, as do the practice questions. Although Organic Chem is a subject that tends to fly over my head (and at least a few others), you do well in not making it complicated, but rather simplify it and ease students in understanding this foreign language. In terms of function and aesthetics, the website is great!
Une grande aide!
Much thanks!

Chads real cool and gets straight to the point no matter what topic. His plug and chug techniques really go a long way. I took Physics 1 this summer and because of Chad I was always ahead of the game and prepared for every quiz/exam. Real props to Chad, wish I discovered him when I had taken Gen Chem.

I’ve been using chad’s videos (including general chem, orgo for ACS, and biochemistry), and those videos are saving my life!

I wish you had been my professor when I actually took this course. You are the best! I bought the monthly access to Gen Chem and Organic Chem and I am so so so happy I did! Extremely helpful, plenty of questions to review immediately after learning about a topic. Would recommend to everyone who wants to have fun while learning chemistry 🙂

Excellent Review of concepts, with examples!

I Love watching Chad’s videos. His lectures have been instrumental in re-learning chemistry concepts that I’ve long forgotten! I especially enjoy how he relates the content with realistic scenarios so that I can understand the content better. The quizzes at the end of each section really help cement the content in. It’s even more helpful when the explanation, along with a video is provided for each right or wrong answer.
I am extremely grateful and thankful that he not only takes the time to make these videos, but he does it in such a way that it’s easier to learn and/or recount past teachings. I highly recommend his videos to anyone and everyone needing refresher’s for hard chemistry subjects or for those who want to gain a better understanding of content learned.
Thank you so much! You’re heaven sent!!!
