Hello,
Yes, you are eligible for Round 3 (Mop-Up Round).
If you get a seat in Round 1 and choose upgradation in Round 2 but do not get any new seat , then:
Your Round 1 seat remains valid .
You can keep that seat and still participate in Round 3 if you do not report or join the Round 1 seat.
If you joined the Round 1 seat and got no upgrade , you can still go for Round 3, but your Round 1 seat will be forfeited if you get a new seat in Round 3.
So yes, you can go for Round 3, and your Round 1 seat is safe if no seat is allotted in Round 2.
Hope it helps !
