Could I still sit the STEP exam regardless of which university I apply to? Also how does the whole process of entering to sit STEP work? My AS grades weren't as good as expected, and I plan on retaking a couple of modules, I definitely know that I am capable of achieving top grades in maths and my school has a strict grade prediction policy, therefore I'm hoping STEP could save me if I don't end up getting A*s and try adjustment next year?
