Hi Sourav,
Jadavpur University has already brought out the merit list for all it's courses. It is from among the names in the merit list that the rank cutoff is published for admission. Ideally, there is no second merit list. However, if majority of candidates in the merit list do not take admission and seats are left vacant, there can be possibility of another merit list.
