Hi Pankaj,

With 57 marks I would conclude that your rank must lie between 25000-35000. With this rank and your SC certificate you can definitely make it to the Jadavpur University's computer science or information technology branch. Apply for your counseling positively. Also these are some best colleges under wbjee, if in case you want to further proceed with your choice filling.

1. Jadavpur University Kolkata

2. Kalyani government college

3. Haldia institute of technology

4. Jalpaiguri government college

5. Bidhan Chandra Krishi Viswa Vidyalaya

Go through our site and search for these colleges, you would get every information important for you to know about any of the college.
