Most likely. Your hsc assessment marks make half of your hsc mark. So you're getting 50s-60s internally (assessment mark) if you get higher than 60s externally your mark will increase. pushing you into 60s and 70s. You have to get a high mark externally which makes the other 50%. :)
That would most likely get you mid to high 60s. This is due to school ranking and your subjects as they are not very high scaling. If you don't mind me asking. What are your HSC assessment marks for each subject? :)
It should be scanning and learning (I don't know though). Scanning and learning is often taken by new businesses who want to scan (observe other businesses) and learn (develop skills and ideas to use in their business).
