Love Professor Nowicki's enthusiasm and clear explanations! He's an inspiring guy who will make you exited to learn more about the science of life! I just wish it was longer and updated a bit. It definitely helped me pass my biology CLEP exam though, with some help from CrashCourse on YouTube, Khan Academy and some other study materials for just a few things that weren't covered. That said though, I'd totally recommend this to anyone who would want to use it for self-study or just curious to learn more about biology!

This course is more exciting than most of the series I've watched through my lifetime. Kudos to professor Stephen Nowicki. PS: The cliffhangers at the end of each lecture were killing me.
