Shrike said:Laya, why don't you ask your teacher this sort of thing? The teacher would tell you that 4931 is considered somewhat, but not terribly, more difficult than the MCAT. Importantly, he or she would also remind you that a majority of our students do not see significant improvement until the fourth diagnostic test. He could also look at your individual performance to see whether there is a specific problem that you ought to address at this point.
Yours is just one instance, but this sort of question arises regularly; my response is intended for everyone who is contemplating asking this sort of question, for which the best resource is someone who is not reading this board. The best person to whom to address a question about a Princeton Review diag is a Princeton Review teacher. You paid about $1500 for their help; you should take advantage of it.
I'm guessing you've already asked your teachers, and are looking for still more reassurance. If so, no problem, though you should be sceptical of the value of any particular answer you get on here. If you haven't asked the teachers yet, you should do that first.
