Hi, I'm doing 4 A levels: maths, physics, biology, and computer science (self-study for computing). This past month has been very intense, I'm struggling a lot in maths, and I am currently doing very well in biology and physics. I am looking for advice if it would be wise to switch to core maths because I'm behind in A-level maths, and It's taking too much of my time and I am unable to focus on the other subjects. I would also like to ask if it will affect my progression into doing computer science (maybe physics) in college or apprenticeships.
