Although i didnt opt botany this year a blunder but i tell you i opted botany last year only with one night preparation a typical UAF approach and to my astonishment i secured 120 while paper was liable to be failed in only paper 2 i got 70. Dear i assure you if you people have just opted all four questions no reason that you get 150plus a very high scoring subject this is. If ce2013 result would have been announced before application submission of ce2014. I would have continued with it. Anyhow all the best for your scores
