Hugely regret not trying hard at GCSEs.

GCSEs I was slacking off and hanging around the wrong groups of people. My grades were:

Maths -5
English - 5
Science - 5-5
Computer Science - 7
Geography - 6
Business - 6
RE - 5

If I could go back in time I would've tried way harder, and I've been recently beating myself up about it.

Failure is not the end. It's what you do next that counts. I know so many people who got straight As and got into the top schools like UCLs and are complete morons. (if that helps). Good luck with A Levels!

Hey I feel for you. I went through the same thing and I too wished I actually tried harder during GCSEs but what I found was it could only get better from there. Realizing and admitting this is the first step. Focus on your A levels now and if you really need to, retake some of your GCSEs. Don't beat yourself up. It's what you do next that matters.
