hi,

see government colleges of west bengal takes admission based on wbjeeb score, howeevr cutoff score changes every year and it depends on certain factors like number of participants, questions difficulty level, seat matrix, candidates category etc, now at this score you have less chances for tier 1 colleges even for your category, so I suggest you to give more sincerely jee main april session exams. you may use careers360 jee main knockout program to boost up your performances,
