Hello, I hope you are doing well

Since you have not been allotted any seat till the 2nd Extended round, chances are almost negligible for you to get a seat through KCET. You could still try your luck in MOP UP round provided that it happens, because MOP UP rounds only take place when seats are left.

If you are willing to drop a year then you can prepare well and give the exam again next year. Another option is to get admission into a decent private institute in your home state, because it's not the end of the world you can still do your grind and achieve great things.

Hope this helps.
