memory~~

currently studying probabilities of events that i have studied before in secondary school...it makes me recall, i not sure during form 4 or 5, when we have to study all this in the modern maths...

as usual, i didn't listen to what the teacher teach...plus, i am lazy to study myself, and so ngam, fei kang was sitting beside me in the library...so in the end, he teach me.

this is what i learn from him...and whenever i see this, i will remember the 'gao cha, gao cha' thing he said...haha


and this is what we called, memory...=)
