Hi Ayush Jha ,

In my Opinion you should only go to these coaching institutes if one are in their Top Most Batch else you should not, who would know better than me i myself being a previous student of Resonance Kota, the other batches they all are useless as they do not have good teachers in those batches.

So you can do one thing that is ask for demo classes for both JEE as well as for KVPY and tell them that you want demo classes from the same teachers who will be teaching you later on
