Hi Aspirant!

According to the CSAP rules, candidates can change the academic preferences only when it is allowed by the authorities. Last date for Trial Allotment & option to change the academic preferences already submitted  was on 22nd August 2021. Tomorrow first allotment list will be displayed to candidates according to their preferences. If you are not satisfied with the seat allotted to you, then you can choose the option " Accepted & Opted for Sliding" this option is for the candidates who wish to upgrade their seat.
