Which is the best optional along with the best coaching??? Does it exist or its like the mythical Atlanta! Coaching mongers are dumb, they keep advertising GS and current affairs, when the real mountain is optional. People who dont get selected lack mostly in optional, GS numbers are not in one's hands (in my opinion).
After 4 attempts, I am looking to change my existing optional (its a science one _ BIG MISTAKE). Please tell me the ans to this most important question.
