how much marks should I need to get CS branch in Jadavpur University ? what is the average package of CS branch ?? Is it tougher than jee mains.

Hello student I believe its not fair to compare two examination of same level which is more hard or easy the syllabus of both the entrance examination is same you need to prepare for both of them and practice a lot of question so that you'll learn new concepts and solve them as fast as possible.

The average placement of Jadavpur University for CS graduate engineers is around 8-10 Lakh per annum, placement may vary from student to student on the basis of their academic qualifications and skills.

Feel free to comment if you have any doubt
Good luck
