Having some friends at Jadavpur University, I can list some problems that students usually face:

1. As Jadavpur University is a regional university, it lacks the exposure what central institutes usually attract. For the same reason, the administration is a little lazy and students enjoy too much freedom. 
2. Most of the professors are quite qualified and experienced, you can find a lot of them who aren’t up to the mark. Here, it becomes quite difficult to compete with the level of IIT and NIT professors.
3. Students at Jadavpur are not creative and do not think out of the box. They usually like to go with the flow and simply follow the syllabus for good placement. 
4. The placement scenario of the CSE department might be at a height but sometimes, other departments suffer and couldn't get as great opportunities.
5. The UG research quality in JU is not up to the mark. Although many students indulge in research and projects, the publication quality is not at par. They just make some small change in an algorithm and produce two/three papers but are not recognized very kindly by foreign universities.

All in all, JU needs improvements with the serious involvement of all the students, teachers, staff, alumni of JU. By tackling all the problem areas together, it can shine like IITs and NITs in the near future.
