for me it was like 5 or 6. i never worried about it but i guess that's bc i never really thought to. i was fine in class and you will be too. the ppl who took it a year or even semester before we started were a little ahead in some spots (little things that once you see/read again you'll remember) but there's so much new material that it evens out.
tl;dr: don't worry now, you'll have enough to worry about later when you're learning all the origins/insertions/palpate points etc.
congrats on getting into school!
