In Need of Studying Tips

I’m in full swing with my midterm exams and I’m having a little bit of trouble. Tomorrow is my bio exam and I am starting to freak out a little bit. There are 5 chapters of which 2 I know almost nothing about because they were early in the year and another of which I am not super familiar with.
For my spanish class I can just study this little packet the teacher kindly made for us but for biology I am a little stuck.

For the past few years I have been able to just look at my notes and somehow memorize them, but it’s not working with this class for some reason. It’s like my brain refuses to soak in any more information. Of course I haven’t filled it up that will probably never happen.
I have my textbook and piles of notes and, of course, the internet.
What are some studying methods that you guys use?

I would be grateful for any suggestions.

Thanks
