How do you get interested in biology?

Some sections might be tedious like diversity, ecology, etc. However, you will still need to complete them because they are on the course list. The best way to remember these kinds of parts is to come up with mnemonics for variety and classification. Stop what you are doing and focus on something more interesting than ecology or comparable topics. If a chapter is really dull, you may always watch a video instead. It is true that pictures may speak a thousand words.
