hi,

, cutoff score changes year to year and depends on certain factors like number of participants, questions difficulty level, seat matrix, the stream you may opted for. if you want to go for bsc in computer science , cutoff score is calculated for any one language subject+ any other 3 subjects of 12th course. for bsc in computer science it is mandatory to have mathematics as a subject in 12th course. however there is no advantage just having computer science as subject, rather it depends on your score you have got in 12th exam.
