My CHEM191 mark wasn't scaled:
Exit tests = 30/30 = 15%
Terms test = 30/30 = 15%
Final exam = 97/100 = 67.9% (agree that that was a seriously tough exam by the way)
Total = 97.9% = 98%
Final mark on PIMS = 98%
The only one of my marks that I know to have been scaled was BIOC.
Having said that, some scaling did occur in other papers. I just know that it didn't affect any of my marks - for example apparently there was some scaling in PHSI191 but that didn't affect me - I had 100% before and after. Also apparently that was just minor, and around performances far lower than A+.
I loved BIOC, and not just because of Tony. It had the relevance of HUBS but was more interesting (especially module 6 :drool

and actually required some genuine thinking, rather than just being spoonfed.
