Ready for CLEP Natural Sciences?

[Valerian]

[COLOR="#800080"]Hey hi,
So I just took the CLEP Biology, English Comp., American Lit and College Mathematics at the end of last week. I'm hoping to be ready for Intro Ed. Psych, Intro Psych, Natural Sciences and Intro. Sociology at the end of this week.

While I know I will grasp the social sciences easily, I am a bit up and down with Natural Science. My scores are pretty consistent, but my feelings about the exam fluctuate. I scored a 67 on BIO, I took the 8 Practice NS questions on the college boards site and got 8/8 correct. On the free-clep-prep's practice exam for Bio I scored an 82%. I just took a Peterson's practice exam for NS and scored a 62%.

I don't consider myself very science-minded at all. I spent 2 weeks studying Biology and frankly I was terrified to take the exam. That's why my score is such a shock to me. I'm tempted to spend 8-10 hours a day for several weeks studying for NS, but at the same time, I want to take the exam while what I do know from BIO is fresh in my head.

So what do you guys think? Based on my practice and bio scores, should I just move right on to preparing for the social sciences and take the exams Friday, or push them off until next week and spend a few more 8-10 hour days on NS?

Thanks![/COLOR]
