Again, good use of substitution bro :)
But partial fractions and hera-pheri with numerators was fresh in my mind :D

True.
Partial fractions don't usually work well in the IIT. I screwed integral last time because of partial fractions.

Btw.
Have you started Physics and Chemistry preparations? =S
I'm yet to do either. I'm more into Math for January cause of huge amounts of University work. I'm hoping to dedicate February for Physics and March for Chemistry. =)
