Messed up my chemistry A2 prac exam

This year for A2 I have 2 prac exams, and I started one of them today. At the END of the 2 hours I realised that I measured one of the solids wrong right from the beginning which will ultimately affect all of my results.
I spoke to my teacher who said we don't have time to redo it and he said I'll probably lose 1-2 marks as my yield will be off, but am I not going to lose marks for my titration and ratio in my calculations being wrong ? :frown:

confused.
I feel miserable as I need an A this year and I can't believe I've messed up on something so little :frown:

I still have my other Chemistry prac to do which I can hopefully not mess up, and the titration to do and the booklet to fill in for the one I did mess up - I just hope that this doesn't lower my grade in my practical too much. :frown:

Can anyone tell me anything to make me feel better? lol :redface:
