The ones in the poll seem a bit forced, in my humble opinion. I personally suggest going for something more classic, like:
- No. 1 Study Guide
- Students' Study Guide
- The Study Guide
Another suggestion was Paper Tutor. Thoughts?
I like those, I REALLY like Paper Tutor. anyway yeah I voted but only because I couldn't think of anything better, but none of the options sounded too great to me. You can stick a word people need to look up in front of the name, but it they sound a tad pretentious tbh.
The study guides are written by past students right? and that's the reason they're so helpful, because you get a successful student's perspective, right? How about something along those lines;
past students study guide,
high achievers VCE guides,
ex student guides,
ex study guides,
Tutor X 
or something along those lines
