Hello Merin Rose

I hope you are doing good . I am very very sorry to inform you that CUSAT doesnt offer courses bachelors of sciences in any stream so their wont be any entrance for this course . Moreover, courses offered by cusat for under graudation are BA ,LLB ,BBA , BTECH , BCOM ,BVOC . I would suggest you to go for ISI entrance to get admission into top stats college . Following is the link of brief details of CUSAT courses
