Applying early

Hi! I had a few questions on applying early. I want to retake the SAT in October just to see if I can get my score up a little. I want to see my scores before I send them to colleges but will my scores get there in time? Most colleges allow scores to be sent 2-3 weeks after the initial application is due but is this enough time for me to see my scores and decide which ones to send? Should I just apply regular decision? Thanks!

Yes the October SAT scores will be sent in time. You will have 2-3 days to choose what scores you want to send if you want to make the November 1 deadline (and if the college is strict about the deadline).
Some colleges allow you to send November SAT scores as well, but it depends on the school. You have to go to their website and check their early admissions policy.
