I have been helping science and pre-health students excel for more than two decades. I have spent most of the last 15 years managing the tutoring facility for the Chemistry department at one of the largest universities in the country and continue to work there to this day. I help thousands of students in person in large groups, in small groups, and one-on-one every semester and this site is my attempt to help far more. Chemistry and Physics are not as difficult as you think...I promise! Try one of my FREE or premium courses today! Happy Studying!

Chad's tricks and explanations to chemistry made me wish he was around when I first took it years ago. I would have aced those classes without stressing as much as I did. If you come across his review videos when you're having a hard time, watch them! His videos are the best resource you'll find for chemistry!

Okay so obviously this isn't the best case scenario but I crammed a semesters worth of chemistry in 2 weeks and my final grade was raised a letter grade higher! Chad is really great at explaining things! I will be continuing to use his courses for help with the rest of my chemistry classes!

When I took General Chemistry 2 the teacher was brilliant but had no understanding on how to relate the information to a student. After 16 weeks in his class I hadn't learned a thing. Chad is able to explain the material on a student level, not a Phd level, and makes the material enjoyable.

These videos have been so incredibly helpful to me in my first year physics courses in university. I have no physics background at all, and have been struggling big time. If I would have known that these videos were available in the first half of the year long physics course Im required to take- I would have dived right in. Thank you for these videos! I've been recommending them to everyone I meet. Thanks again, Chad! You're teaching style and examples for all of the courses you cover have been a God send to me :)

I spent most of my time during the summer trying to study and cope with my Organic Chemistry professor. He did not bother to even teach, so I decided to go with the textbook that he recommended instead of teaching to the students. I failed the first test, so I thought my life was over. However, I heard from my predental friends that Chad's website can help, so I gave it a try. I really enjoy his course, and his replies from my questions helped a tons!

For me, these chemistry videos gave me the confidence and joy in learning chemistry for the first time. Chemistry was always that subject that I just kind of dodged. Somehow I was never able to understand the chemistry taught to me in high school and college four years ago. I got so frustrated with just memorizing things and not understand a single thing about what was actually going on. Learning from Chad has got to be one of the best decisions I have made, as he has turned this subject into something I am looking forward to learning about and teaching me foundations that have been long overdue. I am not one with the videos yet, but I have to say they are truly wonderful. -Shannon
