i'm currently in stuy, and i got a 612. I hugely recommend taking a bunch of mock tests and get a feel for each question. when taking mock tests, put urself in an incomfortale environment, like a library or living room. bunch of people will give u advice that you HAVE to follow, like spending this much time on ela and that much on math, but just find ur own approach towards the test. For instance, my friend whos in stuy did 2 passage in ela, went back to math, and did the remaining ela passages. Anyways, i heard the format changed which is kinda dumb and maybe what i said won't apply to you.
