    Using 4U knowledge in 3U exam?

    Can i use 4U techniques in the HSC for 3U or any other 3U exam?? For Example: find area of a curve y=ln(x-1) from 2 to e+1. Its worth 4 mark and require integrating ln(x-1), so could i just use integration by parts and get the answer or do i have to do the 3U way of find in terms of y?
