The quality of these videos is great. They each come in two versions (low and high quality). I highly recommend the site.
Range from low entry calculus to high level calculus and each video is very thorough in explanation.
You can watch them on your browser or download them and watch it on your iPod!
Don't thank me, thank the site lol.
