Hii Ajay!

You need to mention the subject combination for which you want the NERIST 2019 question paper of NEE 2. Also, you will get the question paper for this on the official NERIST website, as most of the colleges and websites provide previous year question papers and sample papers to students for practice. You can also refer to the digital library of the Institute  if available. The link for the official Website is provided below-

Hope this helps.

Good luck!
