10. ### A couple of questions regarding moderation.

1. If I am the only student, say in Math Extension 2 class, is that mean I can stuff up my internal assessment (i.e. the teacher may set very hard or very easy exam just to warm up) as my internal mark would be adjusted according to my HSC mark anyway? If I am the only student, isn't that I...
