I got 71 in slot 3 GEF. What are the colleges should i apply for?

You can apply to ISB's new YL program. If you are interested in HRM, then apply for TISS Mumbai. These few reputed colleges will probably close their forms by the second week of December. Hopefully, you have also applied for IIFT, MDI, SPJIMR, and FMS. Baki, wait until the final results are out.
