hi,

In official website  there is not much resources available for question pattern for b.sc admission. based on qualifying  exam score students are shortlisted for interview. however you may study from the questions papers of banaras hindu university entrance test or text books of pcm, if you have taken preparation for wbjee or jee main exam you have an added advantage. there is some book stalls near jadavpur university gate, you may go there and ask for previous year b.sc papers.
