Hello,
The cutoff marks for jee mains 2017 was 81 for general category,49 for obc category,32 for sc category,27 for st category and 1 for pwd.
However,it varies every year according to the level of questions asked in exam and number of students appearing in the exam.So you can plan and prepare accordingly.
Good luck.
