For just 1 more minute,

I think i am really dumb
i am suppose to get the whole physics spa skill 3 correct
but because of the stupid constant thingy
i think i will get 1 mark deducted!
what a waste!!!!!
I myself even reminded haozhe abt how surface area doesn't affect friction
however,he didn't believe me & checked it out with mrs peh
& she said,"ya although surface area doesn't affect friction but it's gd to keep it constant".
upon hearing that, i changed my mind & followed what she said
I wrote that down as 1 of the constants
everyone told me that's not right
the more i think about it, the more i think they are right
i feel like killing myself for making such stupid mistakes during spa
I should never trust them again~~>.<~~
