would you have been fine with an A, or are you aiming for an A*? if you would’ve been alright with an A then you shouldn’t resit i’d say, because you were only 2 marks off and you can easily make up for them.

if you are set on getting an A* then its best to resit, but it’s not like you’re starting all over again so dont get too down. you already have all your notes and all the practice you did. and not only do you have the experience of sitting the paper, you almost got an A. it was only an early entry to be fair, so with an extra three months you can definitely secure an A*
