Dear aspirant,
As you have mentioned that you have got 23k gmr in wbjee entrance examination so you want to know your tfw rank so let me tell you that this rank can't be predicted because every year it differs as the number of candidates applying for it is different.
Coming to the second part of the question, your rank is such that it won't grab you top colleges lile iem, haldia, heritage, Jadavpur but it would give you future institute of technology.
