Should I take the SAT next year in 10th grade?

Hello, everyone :slight_smile:
I’m planning on going to UCLA in 2018 after high school. 9th grade is almost over for me. I was thinking about taking the SAT or PSAT in 10th grade to get a head start. Would this increase my likelihood of getting into UCLA? Which test should I take next year?

When in the next school year would you take the SAT? Just a reminder: The new PSAT format will be administered this upcoming fall.
