I STRONGLY recommend that you get a “coloring book” for biology courses, particularly for cell biology.
I took the course 498 years ago at UC Berkeley and used this coloring book:
​
Got an A but wouldn’t have if I hadn’t used the coloring book. I used colored pencils and color-coded what groups of colors referred to (reds, greens, blues, etc). When exam time came, I‘d often close my eyes and visualize the colors and diagrams.
Granted, I’m a very visual learner...
Before you begin coloring, I recommend that you come up with some kind of color-coding scheme.
BTW—I still have the book. The Cell. It’s come in handy to refresh my memory related to COVID 19.
I was talking about the Pearson coloring books. This is the book we used for assignments in my freshman biology class and This is the book we used in my Anatomy and Physiology class. I actually asked for this one for my birthday not realizing it was the same line of books.
