The overall difficulty level of the paper was somewhat close to that of previous year's, though a bit difficult I'd say from the previous year.

So, by going according to that of previous years “ rank vs marks” you can definitely get a secure space for the best deserving colleges.

So going by 70–80 in wbjee this year, your rank should definitely lie in “5k to 6k”

All the best

If anybody wants to know his approx. rank according to his marks, just comment down below .
