It shouldn't even matter. They only take your best 10 units for your ATAR anyway - it probably won't count for you, since you're doing so amazing in your other subjects.
I don't like the progression of:
quadrilateral, pentagon, HEXagon, HEPtagon...
There's something about those two H's I don't like.
Therefore, Pentagons are better, clearly.
Actually, now that I look at it - it is a bit off. It says only 15 people got 99.95.
I withdraw my original statement. Sorry, Barbernator.
Edit: Actually, It's way off - it says only ~13000 students for the total.
Surely there's some tutorial on Youtube or Google somewhere out there for this? :/ This would have to be the most famous science-project ever? (after the infamous volcano...)
