Hi, one question about my test scores

<p>Hi, I practiced myself with sparknotes, CB Math SAT IIC, Kaplan, Barrons, PR and I usually got around 700 or higher. (some of them, I got better, but some of them I didn't)
However, since I wanted to do better and solve more practice problmes, I bought Meylani's 15 Realistic Tests for the SAT Subject Test Math Level 2. I took 3 tests, and it was the hardest test I have ever taken. I don't know like 10 to 15 questions.
What is going on?
Anybody know?
(what a weird question...)</p>

<p>Anyways,
I want to solve more problems and prepare myself more.
Do any of you guys know good prep books?
Thankx.</p>

<p>Meylani's tests are death in question form. If you missed 10 and got the rest right, then close the books cause your getting a 800</p>
