I think https://codefights.com/ is a very good place to practice. There are so many practice modes you can test your skills. You can challenge with strangers, bots, you can view interview questions of companies. You can join tournaments etc. I think you should check it
I do agree, everyone must be facing this problem at least some point of time in their CP.
Thatâs some progress man, Keep up ! (Takes note of the above links) 
JEE has no connection with CP infact people have different tendencies for JEE stuff and some for CP, doing JEE doesnât strictly mean you will be good at CP while the others wonât be (though itâs expectation of parents) still stand strong for what you have 
Everyone here is awesome and helpful !
