Hi Guys just started year 12 and picked up Extension Science as kind of an impulsive subject. Currently this means i'm doing 13 units which honestly I don't think I can manage. I have 2 options for this ether drop bio and keep ext science or drop ext science and keep bio. It's almost impossible to find any info about extension science and I have no idea if it scales well or is worth it. I picked it up believing it would scale well and was generally enjoyable. Anyone have suggestions on which subject to keep? Or should I keep both even though they may not count towards my ATAR?
