hi fellow friends!
i’ve come to think about when i should take my SAT, and here’s the plan:
i’m a rising sophomore, and i can take the SAT either in Oct, Dec, March, or in the summer (regardless of year)
i have pretty much finished all of Alg2
my question is, should i take the SAT on Dec1 of this year (it would mean so much less stress in junior year)
can i start prepping now, or is it too late?
i am a hard worker 
please experienced friends, help me out–it means so much to a confused high schooler
That is probably a little early.
There are 8 free practice tests on College Board (and the same ones on Khan Academy) as well as more recent QAS copies floating around the internet. When you have prepped and are getting scores on practice tests around where you hope to score, only then take an official SAT. Sure it would be nice to be done with this aspect of testing earlier rather than later, but some kids don’t peak in scores until spring junior year or fall senior year. Let practice test scores be your guide.
Also note that if you are a high scorer, you might as well wait until junior year and kill two birds with one stone by prepping for the junior PSAT/NMSQT (and for NM, you’d need a more recent SAT score anyway).
If you are dreaming big, wait till Junior year (assuming you don’t get screwed over by an easy SAT like me lol) since you will have more practice. The PSAT should be a breeze if you study for the SAT. I’d use Erica’s The Complete Guide to and the ivy Global practice tests as well as the 8 from CB
Does your school offer the PSAT to sophomores? If so, I’d suggest taking that first and see how you do and go from there. If you do amazingly well, maybe go ahead and do a little prep and take the SAT in March or else next August (if you are taking Precalc this year, I’d recommend taking the Math 2 subject test next June if you might be applying to private schools or if you know whether your state schools recommend them).
If you do pretty well but not amazingly on the PSAT, maybe think about doing SAT prep over next summer and early next fall and then taking the SAT next October or December.
lovely advice! @evergreen5 @washugrad @Just a Korean
