3 or 4 A Level Subjects?

I am going to enrol in a private university college in the coming months and I am just wondering, would it be better to take 3 or 4 A Levels. My fourth subject will be Further Maths but I got an A+ in my Add Maths SPM.

It’s really up to you - whether you can handle four subjects and whether you want to learn something. Most people will take 4 subjects.
