I finished my GCSE's and I'm starting A-levels in a few days. I chose maths as one of my 3 A-Level options, although, I feel it may have been a mistake because I did intermediate tier maths for GCSE, I got a B in my numeracy and maths which is the highest mark I could get but I feel I will quickly crash due to the lack of higher tier math I know. So my question is: Is a-level maths reliant on higher tier topics from gcse or will I be fine with the knowledge I currently posses? Thankyou
