Some help// advice is needed!!

Long story short I am really good at physics but sh*t at maths (no it not exaggerated) I seem to click and understand what to do even in the maths part. But when it comes to maths alone I struggle badly I have some strong areas such as Trig and algebra but everything else is down the drain.

But to carry it on in A-level I need a 6 in maths but since I am foundation the max can get to 4.
HAS ANYONE GOT ADVICE ON HOW TO GO UP GRADES IN MATHS? OR HOW TO REVISE? - REALLY NEED IT ONLY HAVE UNDER 10 MONTHS TILL GCSES'S

First off talk to your teacher or the head of math about the foundation. No matter what you do if you do a foundation gcse you can't get a 6. Try to persuade them to put you in for a higher maths GCSE. I would do this by improving in class a lot and doing past papers and showing them that you have improved. (Ideally, do higher maths papers so that they know you are serious about doing higher maths.)

Revision tips:

Do a past paper. (Higher)

Mark the past paper and see what you have failed at.

Revise the thing you have failed.

Do another past paper and see if you have improved.

Repeat until out of past papers.

Then just answer lots of questions out of the textbooks.
