“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 ”

“This general chemistry review was the first purchase I had ever made to prepare/review for a course, and I NEVER leave reviews on anything, but I just have to say that this is the best course prep out there! I watch Chad's videos because not only are his analogies hilarious and effective, he gives off the most positive energy and I feel inspired to learn chemistry because of him. Thank you for being such a phenomenal instructor, Chad! ”

“These lectures help me understand my textbook and professor better. Chad covers every type of problem you could encounter on an exam and makes sure to use the same wording that a professor or textbook would use. This last point about wording is extremely important because certain phrases indicate how you should approach a problem. If you don't know what certain phases mean, then it becomes increasingly difficult to know which equation to use and what exactly you are solving for. So my favorite thing about these lectures is how they address this issue. Additionally, Chad provides a lot of shortcut equations that are really helpful and necessary to know if you want to finish your exam on time. ”
