Am I kiasu?

Assignment due end of this week. Some spreadsheet calculation thing on business stats. I've got all the answers except one question, and that question carries the most marks. *sigh*

None of my friends seem to know how to do it, and even if they say they do, their explanation is totally rubbish, and is outrightly WRONG. And I'm getting so stressed up. Some friend said "It's just 8 marks out of 100". But...I cant stand not getting that 8 marks!

Am I kiasu or what...!! Grrrr....
