For non-Keralite candidates, to get into CUSAT, you need to secure a minimum of 60%. CUSAT has campuses in Kochi and a remote area of Alappuzha district. For a rank under 2000, you will get admission to the Kochi campus, otherwise, you will get into the Alappuzha campus. I would suggest you work hard and get into the Kochi campus. To get into the Kochi campus, you will have to score a minimum of 60%, and to get a good branch like CSE and Safety, you will have to get more than 75%.
