Today go NUS [LT 25] for Smo 2nd round. About 200+ ppl taking.
It seems that this year is somehow easier than last year coz last year I can only do 1 question but this year I can do 2.5 questions. But haiz, it still not good enough to get into top30 unless miracle appears. 3rd question is quite an easy question. 1st question waste me quite some time. At first I thought it is got something to do with Stewart's Theorem but then later foundout that it is just using similar triangle to prove. Sweat! 4th question I can't prove some of the parts but the formula is known. Dunno whether will cut marks annot... 2nd question I still dunno howda do and 5th question simply rite some rubbish. Hope can earned at least 1 or 2 marks... I think can at least get a Gold Award barhs...
Duno y an unknown kno my no bt dun reveal his/her identity...
