Instructor

I spent more than 15 years managing the tutoring facility for the Chemistry department at one of the largest universities in the country. And I have been helping high school, college, and pre-health students excel in their science courses and on their entrance exams for over a decade online. Chemistry and Physics are not as difficult as you think...I promise! Try one of my courses today! Happy Studying!

What Students are Saying

“Learned so much material from this course. Explanations are right to the point and the quizzes really bring things together. Simple and sweet, yet beautifully detailed. Thanks Chad!!”

“Hey guys, so I found out about chad a few years ago when i was in high school and trying to get ahead. I used his videos for him to explain concepts and problems i could never understand in class. Now I am currently taking Organic chemistry and I havent been to class in over a month or two and only watch Chads videos and i still get almost perfect scores on the test. Chad is great. USE his videos and take notes. ”

“First time I took organic chemistry I got a 58 on the first test. Now using this the second time around I got a 90. Suggested this to my teacher to recommend if students are having trouble.”

“I couldn't ask for a better study resource for general and organic chemistry. Believe me I took these two courses with the best professor at my university and I got straight A+ in both courses. Chad's videos are very clear, straightforward, and informative. His lectures are professional but super easy to follow and understand along with the help from the chat forum. However if you want a quick respond from him, I suggest you to send him an email. He would try his best to help you fully understand the materials. I highly recommend you buy a subscription, which is super cheap comparing to other resources, to help you practice after each videos. I find it very helpful. ”

“I learned more from watching Chad's videos and doing his review quizzes than I ever have from other review sites/ books. He explains things in such a way that they just "click." ”

“I just want to say thank you, because this course is the only thing that I needed for my ochem course!”

“i have my first orgo test in a few days and i would be so lost if it weren't for these videos. i had no clue how to do chair flips and Newman projections until i watched these videos ”

“One of the best (if not the best) professors I have learned from. Highly recommend this course to learn and actually understand the material. If that doesn't convince you then sign up just to see his t-shirts! :p”

“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! ”
