How many marks required to pass the exam

There is no such passing marks criteria in WB JEE though you need to clear the opening and closing rank of colleges and your desired branches to get admission but rank depends upon many factors like number of applicants fill the form, number of applicants finally appeared in the exam, number of questions asked in the exam, difficulty level of the exam, performance of the candidate, previous year's cut offs trends so you need to wait until the results are out but you may check your predicted rank with the help of our careers360's rank predictor
