What would happen if I would not do Irish?will I lose points on my JC and LC?
If you have an exemption from Irish you are fine. But if you don't you will not be accepted into a lot of courses in college.
Regarding points you just simply don't count Irish in your 6 subjects.
I came in Ireland when I was 11 and I am in first year and I'm not doing Irish ...I wanna become a pharmacist..will I be able to get in college without Irish?
Yes, you don't need Irish to get into college if you have an exemption.
