Which companies are best for trial exams?

[galaxy21]

Hi,
So our school has given us few exams from a number of companies, and I was just wondering which ones are best, in terms of difficulty, as well as similarity to the VCAA Exams.
The companies that we have been given are:
- Insight
- NEAP
- ACED
- QAT
- STAV
- TSSM

Also, is it better to do trial exams from the current study design, as more of the questions are relevant, or past VCAA exams from previous study designs, as while some questions are irrelevant, they are the most accurate idea that we can get for the actual exam.

Thank you!

I suggest doing as much practice from vcca as possible then moving on to company papers. They have a lot of questions which are still relevant today.  Some of the company papers are way too easy. Don't spend time doing a lot of company papers.

Given the biology exam is so close I would highly recommend to be doing VCAA exams  (even if you have to re-do stuff) since that is what you will be getting next Friday and it is important to be comfortable with the style of those questions which are quite distinct to the company exams.

It could also be useful to go over your past exams and see what you've gotten wrong.

Second this.

Also, avoid NEAP. Needlessly complicated and often poorly worded.
