Hello,

I hope you are doing fine, With reference to your query,  I would suggest you to freeze your seat in JERC that will be a good option by paying some fees and side by side prepare for your entrance since very colleges accept kmat dont take any risk. If by any chances things do not go well in KMAT then you will have a backup for JERC.

I hope you find this information helpful. I wish you all the best for your future.

Good Luck
