  1. I am in a pharmacy program and I just want to thank you!!!!!! Your videos helped me soooo much! I was able to get through biochemistry because of you! Thank you!!!!

  2. Great explanation….again. It's been years since I studied chem in college, and even though I'm teaching Physical Science at the middle school level, the refresher/review is amazingly helpful. I can't go this detailed with middle schoolers, but it helps to remember the deeper background behind the basics I do teach!
