i had a dream in which i kept trying to recall the formula for summation of r^3 from r=1 to n. i'm going to memorise that soon. i finished reading 'harry potter and the half-blood prince' last morning at 4am. it's such a terrible ending, i don't want it to end like that =( i woke up at 1pm.

now that i've finished reading harry potter, i can finally rest in peace and go do more important things like reading 'newsweek' and 'time' magazines, and improving my gp. i've done as much as binomial expansion for maths revision. so imma start on my carbonyl compounds revision.

i don't want to study for h3 maths test. and then there's gp essay test on monday when school reopens.

inferi are scary!!!
