I have always been wanting to study computer science at a competitive university such as Imperial or Cambridge. But my current grades are 4A*s, 5As and 1B.
The 4A*s being in Maths, further maths, ICT and Physics.
The B was in religious studies and of course a B isn't a bad grade at all, but the main reason I'm dissatisfied is because I ran out of time and threw away nearly 20% of the marks available and then came to be only 5 marks off an A grade.
I keep fearing that the B would one day backfire on me, I can't bring myself to talk to a friend about this without being judged, and I feel like I'm constantly paranoid and sensitive about my grade, especially when comparing with friends, and was even considering a resit of the exam.
What should I do? Is a resit worth it, even for self satisfaction?
