I am currently an A-Level student. In my GCSEs, I got 9888877666A (The three 6s were unfortunately in BioChemPhysics) but I was bad at science anyway and couldn't study because I had to work everyday to support my family. I also had to sit an AS exam in the same summer which I got an A in but I suppose that doesn't count since I chose to do it out of will. Anyway, did having to work from 5pm until 9-10pm everyday count as "extenuating circumstances"? Because if it most likely doesn't, then I won't bother telling school as it is too embarrassing. Peace out!
