HELP! Progressively lower scores on Math II!

<p>Hi there,
I have been using Barron's Math Level 2 book to prep for the SAT subject test that I will be taking on Saturday (YIKES!). However, my scores get progressively lower and lower on each practice test that I take. I started out with scores around 690, however, I continued to get lower scores. The last two practices tests that I took I got a 630 and 620. -.-
This is very unsettling for me because the subject test is in a mere 2/3 days. Also, when I take the tests, I feel like I get the correct answer for them. But, alas I always fall prey to the "dummy answers." I would like to get a good score on this subject test, and my target score would be in higher 700's.
Does anyone have any suggestions as to how I should spend my last nights studying? Also, are there any equations that you feel I should know/memorize for the test?</p>

<p>Thanks a bunch!</p>

<p>hey i’m a chinese and this is my first reply on CC…
i used barron and i got an 800 in maths2. barron is much more difficult than the real test
why don’t you find the OG ,even princeton is much better than barron
i remember i missed 15 questions in practice 4 or 5, if you can get a 700 in barron, i’m pretty sure you can get an 800in the test
keep in mind that you don’t need to spend much time on the conic sections
and be careful cause some problems will be a little tricky…
Good luck</p>
