    My Chemistry Teacher was not explaining things well at all and a friend turned me onto Chads Videos. I love how simple Chad explains the concepts. The videos were short as well so I could watch a video and then do homework problems to reinforce what I learned. I would recommend Chads Videos to anyone.

    Chad is an excellent lecturer that teaches a wide variety of subjects. I have used his videos for both Ochem and Gchem and have been in the top of my class for both. I would say that Chad was better than both of my real instructors.

    I actually found this course after already finishing my first semester in general chemistry and honestly this is so much better than learning straight from the textbook. Chad only gives the information that we really need to know, whereas the textbook would give you everything and you will have to decide what is important and what is not. I suggest watching the video on a chapter then solving as many problems as you can from your textbook from that chapter.

    Chad teaches the concepts so well. My professor, although good, doesn't explain the concepts well enough. Instead, he relies on "that's how it works". Chad will explain the concepts in a simple manner that makes you understand why and how. Without him, I would fail. Thank you Chad!

    Finding these reviews truly changed my life. I was in the middle of my chemistry course, getting very low grades, and feeling ready to give up. I watched many videos online and didn't feel like anything was helping. Finally, a friend recommended Chad to me. I watched all the videos for Chemistry 1 until the chapter we were up to. After getting 2 bad test grades, the test I took immediately after starting Chad I got an 88! I was ecstatic. I felt like I finally had hope and I could do well in Chem 1 and all other courses that I could use Chad for! Chad is an amazing teacher and explains the material so well. I truly wish I could have more teachers like Chad. Thank you!

    Chad really dumbs the concept down for you which is amazing because most chem professors and textbooks always seem to add extra info or extend teaching the concept, confusing a lot of students with not only understanding the concept but the math as well. The videos are a decent timed duration so I don't spend hours on end learning like in class. Example problems are worked out, but most importantly the main idea is clearly received and that's what is really important for me.
