At the momment I have 14 units. I have a choice of dropping IPT or History Ext. I do well in IPT but then again it is easy and I am alright at history. Both teachers seem to be providing information on why to drop the other subject. I am a fairly good writer but can't imagine getting in the very high 90's. Is History Ext. too much work for the UAI outcome or is a lower scaled subject such as IPT better even if it is less rewarding?
