get more tanned, wait for my hair to grow longer.

just had maths lecture test today. the topics involved are Complex Numbers, Probabilities and Permutation and Combination.
think i screwed it up.
How could i have forgotten the formal presentation working for answer for quadratic roots of unity, and the general formula for circle!!! i even found out the radius for the circle, but the method to find the center of circle just wouldnt flash when i need it the most!!!
damn it!!! Complex Numbers is difficult!!!

and life too...
