With 212 you won't get any college through AIQ counseling. If you want a seat you can apply for the state counseling but even there it's pretty difficult because WB keeps a high cut off trend every year and this year it's expected to rise as well.
The last option you're left with is management seats. For that you have to go to the private college physically and talk to them. This will charge you a lot approx 40 lakhs + initially. They might give you a seat.
I hope this helps, good luck!
