I heard that when your atar gets calculated and ur on 11 units a 2u subject gets halved. So i just realised i screwed up because i dropped 4u because of the overall workload. But then thought about it and decided that it was best if i kept 4u and dropped bio, since the content is boring me in class. So ill be on 10 units because its the same as being on 11. what do you guys think?
