Hi,

The cut off of the entrance exam varies every year and is based on so many factors such as number of candidates appeared,number of seats available, difficulty of exam etc. It also varies with colleges and courses . From the previous year results the cut off for almost all courses are between 250-350 .So the admission based on the above score is tough. You can check the previous year cutoffs of different BITS campuses in the following article
