Questions on Biology Clep-peterson test

[armyb77]

Ok so I’ve been studying now for about a week. I have taken all of the Peterson Practice Exams and received the following scores: Test 1: 64, Test 2: 64, Test 3: 47. I really want to take the test on Friday but the score for test 3 threw my confidence a bit. Over half of the questions during the third test, I don't remember even reviewing during my studies. The biggest problems I seem to be having are:
1. Looking at a picture and determining whether it is a lipid, steroid, protein, or sugar (some questions ask what kind of sugar or protein things are too???)
2. Neurons and chemical reactions within them
3. Names, Names, Names!

It seems I can fumble my way through a lot, because I can recognize names of things and associate what area they are talking about, but with these scores and reviewing the information I messed on the practiced tests do you think I should be good enough to pass?

This is my last class to close out my Associates with Pikes Peak and Graduation registration end November 15th so time is ticking to get my results in on time!

Thanks
