Hi guys! Right now I'm taking 11 units and my subjects are: 4u English, Legal Studies, Biology, Modern History and History Extension. I'm really stumped as to whether I should drop History Extension or not though. I want to keep it so I have 11 units and some sort of a "safety net" because Biology is my weakest subject and having History Extension means that only half of my Bio mark would count, however, if I drop it then I won't have as much work which means more time to concentrate on other subjects. Could anyone help me out with my dilemma?
