Its surprising sometimes how you can get a highest mark without getting an extraordinary mark yourself. I overhead someone saying at uni last week that they got 78 in Competition Law i think? and that was the highest mark.. was very surprised given that its not far over a D, notwithstanding that I'm told it was a really hard unit.
That said though, when i've gotten the highest marks in law units my marks were 94, 94, 92, 86, 85 so it was a fairly broad range of marks with what i thought were really great marks at one end and ones that were really good but nothing spectacular at the other.
Seems you needed higher marks to get the top in my non-law units as when i got first places the marks were 94, 89 and 88 and they were units that were regarded as difficult. A few friends said that in the business degree I did, they got high 90s in their electives but still weren't top 3.
Haven't heard of anyone getting 100 in anything I've done, well done to anyone who has! I long gave up on ever getting perfect mark and with the prospect of revenue law as one of my units this semester, I continue to avoid that aspiration lol
