Hello Tarun, If you have taken admission in the college you have been alloted in the 7th round, then if you also get a seat through CSAB, you can withdraw your admission from the previous college and go to the newer alloted college.

However if you do not take admission and then proceed to CSAB counselling, since it is a fresh process being separate from JOSAA, you will lose your previously alloted seat.

dear tharun,

If you have freezed the seat you got during JOSAA counselling and not alloted any seat you can definetely particapte in CSAB round and if you dont get a seat in CSAB you can go for the retained seat that you have opted earlier , no issues will be created in doing that.

best of luck.
