Friends, I need ur advice regarding ifos optional. I m NOT a life sciences graduate. I m in dilemma to chose between botany and geology. I heard geology is not faring well(Geography was CS mains optional) .What about botany's success rate? R the Evolution institute's material sufficient to do well in exam? I can't afford to go to Delhi and enrol their classes because of job constraints. But I have ample time after prelims as I m appearing only for IFoS . In that 6 months time, which amongst the 2 optionals is advisable for a non-biology aspirant?
