Gcse maths

If i were to revise just maths every single day for the next 2 weeks, then go back to my revision timetable (only maths and science bc i don’t care about the rest).
I’ve already got a 9 in science so again its not really a priority
Could i go from a 5 to a 7 in maths ????

Yes, I went from a 5 to a 8 from mid March to my exam. Do as many past papers as possible in that revision session. Focus on doing at least 5 past papers every week and try to focus on all three of the papers then JUST calc or noncalc.
Best of luck x
