hi,

see in west bengal the engineering / btech seats for government and private colleges fills by wbjeeb score. now coming to the jee main reservation, around 5 % seats reserve for jee main. so it is quite difficult to predict in which college you may get admission in mechanical as per your jee main score. now jee main april session exam is yet to held and if this time number of candidates increased that have an effect on your current score and percentile. however cutoff score depends on certain more factors like seat matrix, number of applicants, questions difficulty level, students category etc.

you may use careers360 jee main college predictor tool to know about your probable college,
