From what I remember, the lab stations are reminicent of what you saw in the weekly labs. I would focus on the diagrams and what they mean, so go through the labs and make sure you understand all the pictures, and if you didnt see it just
google it. (becuse there will be microscope slides)
For example for the types of gametophyte stages and how they look and where spores and whatver are found...its pretty general stuff.
The lab exam is more identifying and its multiple choice so while you do need to know basic knowledge its key to know what everything looks like becuase they will be showing you live samples! I don't know if you had quizzes this year but go over those beucase they are useful.
I didn't take pictures of everything in lab and googled most of it when I was studying and I did well. Its not that difficult and you have enough time
hope that helps, and good luck!
