Hey, I'm in prelim ATM , doing 13 units, I have 3 unit math ATM, but I'm finding it hard too concentrate on it , I've only done 2 tests do far ( on 2 unit subs ) and scored 89 and 72 . Idk I I should stay in 3 unit and see how I go ( at least for this year) then I ccould dropp to 2 unit, however...
