5 CLEPs in a month

[Aquamina]

I am a high school senior, and am 5 gen-ed courses away from my AAS in Network Technology. I decided back in January I would try to CLEP out of all of the gen-eds I needed before May. Now, it is April and I've been studying for months for these CLEPs and I am about to take my first 3 next Thursday.

Next week, I will be taking American Government, US History 1, and US History 2. I took the AP courses for these, and have been reviewing with online courses, cliffs-notes, and a large amount of flash cards, but I am only scoring roughly 55-60 on the practice tests. I know the passing score is a 50, but I am determined to ensure I pass all of these exams. If anyone has any advice over these I would love to hear it!

In the upcoming weeks after, I will be taking the CLEP exams for College Algebra and Information Systems and Computer Applications. I am not as worried about those as I consistently make 70+ on the practice exams, but I would like any advice that you could offer!

I find that test better if I take them consecutively, it gets my mind in a testing state and I find it easier to recall information taking several tests consecutively, as opposed to on separate days. Has anyone else taken several CLEPs in a single day? I've been told it was unwise, but I'd like to see some more opinions.
