No university in the foreseeable future will ask for S grades in STEP papers(Original post by erratic_deus)
Also, Cambridge does think that a-levels specifically the Mathematics a-levels are rubbish.
Trying to get 100% in a-level mathematics is easy but they don't want this student.
They don't want "churners" or those who are rote-learners. This won't help you with an Oxbridge maths degree.
You should try to get an S or a 1 in STEP!
Focus on STEP or the MAT (for Oxford).
If you perform highly on those, you're likely to get a place!
Honestly that's overkill for any physics degree anywhere
