I personally never took Bio 2EE3!
The memorization is intense, but the first test wasn't really that bad because a lot of it was review. The second test and the exam were harder though. A lot of it was luck, you could not a thousand things but it wouldn't help you if you forgot the [glucose] in the blood :S There were only lecture slides, but these lectures weren't always connected as mentioned before.
However, I have been told that this is an easy course for some, so it depends entirely on you. I would recommend practicing old tests (he posts one sample atleast on learnlink) because some of the questions are similar/ somewhat recycled.
It is a med school related course though, so you should keep that in mind.
If you do decide to take it, I would recommend going to class and just chilling. Everything is on the slides, just concentrate on the information and soak it in, however boring it seems. Your brain can retain the randomest facts
