I'm so confused in resitting GCSE maths in year 13

Guys if I were to resit GCSE maths higher tier paper to try and get a 6 what would happen if I underachieved and say I got a 4? I currently hold a 5 in foundation maths, would that mean that higher tier grade would override my current grade? Is it the same vice versa? If I succeeded and got a 6 would it simply override my foundation gcse grade?

Also I'm planning on taking a gap year so once I get the grades in August next year can I apply to unis. If so, how would I input the new maths grade as it asks for a school, do I just put the private exams centre I did my exams in?

This is soooo confusing I want to cry 😭😭😭😭

i don't know if the higher grade will override the lower grade sorry

did your teacher tell you about it?

This was super helpful

Hi in year 13 for context. Will GCSE exam dates clash with my A Level exam dates? I swear GCSE students go first?

Your best grade counts

i don't know the exam dates
did your school tell you?

Hi, I called UCAS today and the guy on the phone told me otherwise?? I asked him if I got a worse grade than what I got now universities will use my most recent grade. I'm super confused right now and this has thrown me off from retaking maths massively.

The link I posted is from the Times Educational Supplement - the paper for teachers! I doubt it would get it wrong

Then what should I do? I'm getting two conflicting information

I suspect the person from UCAS is getting confused about remarks. For those, if the grade goes down, you lose the higher mark.

For resits though, everything I've read states that you keep the higher mark.

Even if the subject you're retaking is two entirely different tiers. You think it's worth ringing them up again?

Yep, I think it would be worth calling them again.
