Eugh, big mistake imo, I thought that the UK system was better in that a student could specialise and choose subjects they're good at at 15/16.
I had to do maths to 18 as it's a core subject in the leaving cert and it was really hard for me to do pass maths. I failed it the first time and had to repeat. The shame. I got As and Bs in Spanish, English, Art, History and Biology but failing maths branded me STUPID for years. Made worse by the fact that a lot of people around me were doing honours maths in the leaving.
The stupid thing is I've worked in pensions for years, calculating all sorts of things without any problem at all. Pension adjustment orders, actuarial reductions et cetera, I can divide 2 mars bars in to 3 :-p but no, I can't plot the notional mid point between two planets using algebra, but percentages et cetera, no problem. REAL maths as I call it.
Not everybody can be good at every subject at this level (to get in to university). It's ok when you're 7 and it's still relatively easy. But many people struggle with the leaving cert, it's not easy to be good at everything at this stage in your education. A lot of people will argue with me because they found all subjects easy. Good for them.
