Hi aspirant,

The cutoff marks change every year. It's depends upon number of students that appeared in examination, number of seats available in colleges, difficulties of question paper, etc.

According to previous years cutoff you need to score 1734 rank in wbjee to get CS in Jadavpur if you belong to SC catagory.

Previous years cutoff rank for WBJEE:-

General - 107

SC - 1734

ST - 4795

OBC - 456

Hope this helpful. Best of luck.
