hi,

see sastra university has two mode of admission, in stream 1 mode admission is based on 12th score + jee main score, where 70 percentage weightage is given to 12th score, 25 percentage weightage is given to jee main score, however since number of candidates is huge and right now cse is one of the demanding stream in india, you have less chances to get cse in stream 1 mode, in stream 2 mode admission is based on only 12th score, however 70 percentage of total seats fills by stream 1 mode of admission process. so I suggest you also apply for stream 2 mode or again you are appearing in jee main exam give your best for the exam.
