Quantum carries a decent placement record last year it was more than 90% most of the students were placed in multinational companies. Yes, of course, you can join Quantum University, it's a decent place to get wonderful exposure and also helps students to get good placements and it has decent infrastructure and it focuses more on interdisciplinary education and being a student of quantum, it is the decent hub for education:

College is good including teaching staff. This college also provides good placement, and it took participation in many extra activities programs like MUN, TRAIL ADVOCACY, debating competition, moot court etc. Little bit disappointed with the hostel.

Dear Aaryan!
For studying Master's in Economics, my suggestion will go for;
#1) Indian Statistical Institute (most preferred), #2) Delhi School of Economics, #3) Jawaharlal Nehru University. For this, you need maths as a compulsory subject in class 12th. And your graduation should be specialised in statistics/economics or math. Hope this helps. Good Luck. Upvote the answer if you feel satisfied.
