His all predictions are bang on.
I am talking about Amiya's predictor; I know it's complete math, and he is a master of it. Even in iift, he said 35 with higher sectional, and iift followed his wordings.
Vercel is sometimes wrong for me, but Amiay's predictors are bullseye.
P. S.: I don't know how good his other courses but I am following all his predictors, including the PI.
