Hello,

There are 25 different specializations under B. Sc. that Calicut University offers and every specialization has different criteria for calculating index marks. Please specify your specialization in which you want to take admission in so that I can tell you how to calculate index marks for that particular specialization. However, you can still go to this link and check the criteria for calculating the index marks for different courses: http://www.cuonline.ac.in/uguploads/Eligibility_IndexingRules2018-2019.pdf

Hope this help! All the best!
