My maths teacher thinks I should resit C1, C2 and S1 since right now I'm doing C3, C4 and M1 and my C1 and C2 grades are likely to go up to an A if I resit and if I was already going to resit S1 since I got a D. If I resit I could get an A overall if I did well this year too or just a B which I'm ok with.I got high C's in Biology and Psychology and I thought while I'm at it I may as well resit and try and A's or at least high B's so it's easier to get A/B overall this year. Is there any point in resitting or should I just try as hard as I possibly can this year to make sure I get a B overall?I want to do nursing but the Unis I want to go to have higher entry requirements than my current expected grades (BBC). It would also be easier later if I wanted to become a doctor if I had AAA/AAB. Also I'd like to apply for February 2017 so I could just resit and apply for uni again this time next year if they all rejected me this year.
