I get 70000 rank in wbjee which collage preferred in cs branch

• WBJEE has no certain cut-off marks. Securing a positive score secures your rank. Yes, may it be 80k to 90k but you will secure a rank. If you are thinking about good govt colleges and Jadavpur University, then about 2 k rank will certainly secure you a place at KGEC & JGEC where as Some highly preferred branches in JU need less than 1 k rank. That's it. You can check previous year's opening & closing rank here:http://wbjeeb.nic.in/wbjeebcouns...
• Best of luck for your exams
