For me, the toughest thing about AP Bio was remembering so many names of molecules, structures, and processes, and how they all fit together. Any time I felt shaky on a topic, a quick tutorial from SCIENCEMUSICVIDEOS.COM drastically improved my comprehension. The tutorials were super helpful for both review of concepts and memorization. They definitely made it easier to get an “A” in class and a “5” on the AP test.
