Grades for Maths at Warwick to get into Part III at Cambridge

My first grade years were poor, but I could be able to make up for it in the second year

Ideally over 80 percent, over 85 if your first year grades are poor. I know someone who got in with 70 first year but 90 second year. Every person I know with below 80 in second year got rejected, everyone I know who got above 85 got in. Some people between 80 and 85 either got rejected got in norally or got in but had an offer contingent on 80 percent in final year, whereas mine is just to get a first.
