<p>^Doing very well, I mean 2400 / 36 would probably require so much that not many would have this type of time to prep. I do not believe that 2400 / 36 is possible without any prep. We were asked for opinion, here is mine. Doing in a range of 2150 / 33 would require prep., but not that much, about 1 hr / day for a week would be sufficient. 2150 / 33 would be enough for many very selective programs. There is always a balance. Normally, HS juniors/seniors are a busy bunch. It is not worth it to spend excessive amount on prep. to SAT / ACT as there are many great UG programs that will admit a kid with lower score than 2400 / 36. To chase 2400 / 36 is basically being obsessed. But again, this is my opinion, others will disagree.</p>
