mine was about the same, felt i kinda jus blindly bashed my way round GCSE's but came out with great results
for A-level though i was very switched on, A's in physics and electronics...C in maths. i got some of the highest scores our college ever seen for physics and electronics....with a handfull of tests passed with 100%
it didnt make much sense that i was ****** hot at electronics and physics, and then complete ****** at maths. i dont know why i didnt get algebra an the like at the time, but now im at uni doing a masters in mechanical engineering....maths has become one of my best subjects. i scored 68% in maths this year, which is damn nearly a 1st!!!
at this point overall im on a 1st, so hopefully i will finish out the year on a 1st 🙂
