Yes, this has truth to it.No but quite possibly yes. The trial exams are internal exams just for your school, amde by your teachers. They are primarily a 'trial' HSC in the sense that most teachers would try to replicate HSC difficulty. So it may very well be that teachers that are making your tests are going to use past hsc questions or ones similiar.

doubt it.Have you already done everything for HSC course?
Changing a few numbers in old questions in pretty common.Don't forget. Creating new questions are not easy. Unless your school maths dept has lots of talent, I suppose they'll use past questions and perhaps change some of the parameters. It is safer for them this way.
Thanks for confirming my speculation.Changing a few numbers in old questions in pretty common.
