Having a friend who is a student of NITA and attended the counseling of AKTU I think I might be able to answer your question.

He was in a similar situation as you are in right now. His UPTU rank was around 2800 and his JEE Main rank was around 33000.

• According to some research I did, I think NIT Agartala is much better than IET Lucknow in terms of both core and CSE/ IT branches.
• NIT Agartala has been ranked as the top 75th engineering college by NIRF.
• In terms of CSE/ IT branches, the placement scenario at NIT Agartala is much better compared to IET Lucknow.
• In terms of core branches, the placement record is also very good.
• The average package is around 5 to 6 lakh per annum in core branches.
