Does when you take the SATS make any difference?

It shouldn't matter when you take the SATs. The best thing may be to take it in your sophomore year as a practice run, and then again in your junior or senior year. The pSATs aren't really a good practice test for them.

if you take it to early colleges probably won't accept you

Answer 2

Yes it has been shown that SAT prep testing really makes a difference with scores. It boost confidence, and accustoms the student to the ins and outs of the SAT.
