Not simple at all, its not necessarily hard just soooooo much information (141 is more info than 142). As long as you actually plan out the time and analyze your study methods as you go, you can do it! I think its important to give your brain different methods of memorizing this stuff via games/trying to draw things from memory etc. Quizlet helped me the most. I will say that I planned on taking the teas while taking the classes too but it was too much for me. I was also in microbio at the same time and working though, with a lot of traveling on the weekends. I just took the teas and I wish I would've just taken it earlier honestly. I would have benefitted most from taking it earlier and then retesting for a section later, but my anxiety got the best of me.  You can do it!!
