Do I have to resit GCSE maths?

So here's the problem, I will finish my first year in college in England while studying Core maths and getting my qualifications of it. Also studying A level History, Computer Science and Graphics.
Know I'm moving to Scotland, Glasgow but luckily I can atleast finish my first year. The problem arrives people usually pick 5 subjects from what I seen in my research there. I'm 16 but will turn 17 this year. Know I regret picking history, I'm good at it but it's boring and killing my interests.
Moving to Scotland I will probably request to start S5 instead of S6 as I wanna do higher than advance, so far that's my plan. My probability list I would study snd hoped to get is;
1. Higher Physics
2. Higher Biology
3. Higher Chemistry
4. Higher Computer Science
5. Higher Graphics
So next year I hopefully study the advance know the problem arrives I want to do dentistry but I don't wanna do maths so I picked physics over it but I'm worried their will look at my GCSE graded too, I didn't do the best in GCSE but improved so much. Would they care about my core maths grade too? I hope they do well someone answer this question please?
Also, in GCSE my grades were;
Combined Science + Maths = 5 (so 3 grade 5's)
History + English Lit, Lan = 7 (so 3 grades 7's)
So would I have to resit maths for dentistry or can I get away with core maths if I score a B in it? Do I have to resit maths or can I get away with it by getting A on physics? Someone answer my question please it's bugging me off spot and I have not even started in Scotland yet but already so worried about everything.

No you dont but just do higher math instead its more beneficial and desired by med school or dentistry. You have to choose one place my friend- choose eitheir scottish higher sqa currriculum or choose the english gsce and A level.

The thing is sky dear- higher math and english are quite important- many student do them at s5-
you dont need to study higher math for dentistry but it can be seen as negative point because higher math and english are core subject. Higher math is also even more important in your case since your applying to a science like subject.
So conclusively, you should definetly study higher math and english but youre not required to study them. My advice will be to replace graphic with higher math instead.

Core Maths is higher than GCSE - I would ask the unis you might apply to and not rely on advice on here.

Just saw you have already left school and are now at college in England - it is very unlikely you will be able to go to school in Scotland. You will need to look at further education colleges.

I think your first issue is going to be you are unlikely have the choice to enter S5 instead of S6. Council’s are unlikely to want to pay for an extra year of schooling for you if they don’t have to. More than that though, you don’t actually have the right to start school once you are 16, only to stay at school, so they don’t even have to accept you into S6 though they will probably do so. You can do five Highers in S6. The other issue is most schools shift you up a year after summer exams - so you start S6 at the beginning of June. If you start after the summer you will be a month behind (though students do swap courses over the summer when they get their results so there may be others starting then too).
In terms of core GCSEs, I am not familiar with these but you need to look up dentistry entry requirements. They will look to ensure you meet their academic requirements across all qualifications. Dentistry is a very competitive so you will need mostly As at Higher and your previous grades and the fact you are not studying science A levels now suggests you would be wise you consider alternative options.
