I am confused in that Should I join UPES Dehradun or wait for the next CLAT exam?
If you feel you reached the peak of your potential in 2020 law entrance exams (CLAT & others) with the best of your preparation, you may join UPES. Try for good internship options in metro locations like Delhi or Mumbai, which will strengthen your profile & increase chances of final placements via campus or PPO route
If you believe you can put more efforts and get incremental score to reach the top few NLUs, you can prepare for CLAT/AILET 2021 with/without joining UPES. Getting into top NLUs will be worth the effort of CLAT 2021 retake.
All The Best for an informed academic decision.
