I was more or less frog marched into taking Maths beyond 4th year by my teacher and put into this Intermediate 2 course with the view of doing Higher in 6th year but I absolutely hated Maths; I managed to get an A in the Int 2 course which was a much easier course and more clearly laid out; and then didn't take Maths any further. It depends on what you want to do but when I was applying for uni the only subject I had to have a grade in was Higher English, no mention of Maths anywhere. Maths isn't an important subject unless you want to study Maths or some kind of engineering type course. Maths isn't arithmetic. Knowing basic arithmetic, your times tables, how to calculate percentages and that sort of thing is important in later life, but I've yet to encounter a situation where I've needed to know how to use the Pythagoras Theorem since I left school and it's been 4 years now
