I love Chad's videos! I was first directed to Chad's through the Student Doctor Network forums. At first, I was not so sure about all the rave reviews these videos received. At the time, I was not doing so well in my Organic Chemistry class. A little skeptical, I signed up for the College OChem videos. They were absolutely worth every penny! They were organized, clear, and very useful. Chad went through all important parts of the lesson and had very good examples, hints, and mnemonics. I felt more prepared after watching Chad's videos. I have studied for my DAT and bought Chad's DAT Review videos. Again, they are pure gold! He goes through all the important topics and breaks things down to be easily understood. He tells you what is important to know and does not waste your time with all the other stuff. I was a skeptic, but after using these videos for more than one thing I am now a believer!
