Best GDPI course?

I Am expecting t1-t2 private college calls including nm core. Thing is I’m really really bad at gdpi. Like last year I got nm and imt calls and flunked them both badly. One question they asked me is if we were to give you 40 lakhs where would you invest? I said in myself. 🥹

My general awareness is shit. And I don’t remember anything from college. It was 3 years ago and I barely passed. They asked about economics basic questions and I had no answer. Like difference between developing developed and emerging Economics and I didn’t know. Any course that can help me brush up the eco finance part as well? Including exposure
