Test run SAT?

Hi!
I was just wondering if I should take a practice SAT without studying to see how I do on it(the November one), then study and take the January one as my real test? Also, what are the pros and cons of this? Will it effect my college application?Thanks!

Some school require all scores, do you want schools to see scores from a test you did not study for?
If you have a HUGE jump between tests the CB could suspect cheating.
Unless you pay for “score choice” all your test score will always be sent to colleges.
Why waste your money paying for a practice test when there are so many free practice tests available?
