Advice, please

<p>so basically I just finished an SAT Prep class today and took a practice test for it [received about a 2100] ; I did great on writing..OK on math and not so good on critical reading .... well--> a few minutes ago i did three sections of critical reading from the big college board prep book under timed conditions and found my score to be about a 730 vs. the practice test i took today in the morning my score was like 630..now I'm not sure what to expect regarding critical reading. It seems as if my scores differ a great deal everytime. Do you guys think I should take more practice tests for critical reading from the college board NEW SAT Big Blue Book? It's not normal to have this kind of fluctuation on practice exams, is it? --> [my goal is to get about 730-760 critical reading]</p>

<p>what do u all think?</p>

<p>Can't hurt</p>
