really clearly speaking....sorry but you are not the domicile of west bengal as you have mentoned so you can't even fill up the government college which is most prestigious in your list of counsiling  and as far seat is concerned most of government college almost take 95% to 100% student from home state,so according to your rank you can't find even a little better government college for you so also go with pvt college .

fee in college you get through wbjee won't be much high and will have better facility.

hope it helps
