85% of total sanctioned seats are reserved for candidates belonging to Delhi Region . Candidates who have passed class 12 from any school/ institute in Delhi or from any college/institute affiliated from GGSIPU University fall under this category. Seats will be allotted on the basis of candidate’s performance in IPU CET 2019 . Out of total nuber of seats there is a 27% reservation for OBC. Since there are 50 seats for BSc nursing the number of seats reserved for OBC is around 13 . With a rank of 1690 (even if it is general category rank)the chances of you getting a seat in general merit or in reserved seat is not high. We do not know how many obc candidates have applied for ipu cet so it would be unjustified to make any remarks related to what your obc rank might be. There also is an open house counselling at the end to ensure that no seats remain vacant .All the best.
