Hi paidikalayesukrishna. As you have mentioned your scored in jee mains 2020 its a great score to get you admission into national institute of technology but national institute of technology warangal is among one of the top most institute as well as you are opting for electronic and communication branch which is second most opted branch after computer science so its cutoff is very high compared to rest branches so its difficult for you to get your choice branch in nit Warangal.

Hope it helps
