Hi Afna, 

Congratulations on scoring well in your entrance test. Speaking of the cutoff for 2019 in Cochin university, the merit list and the expected cutoff list will be out in the month of June 2019. So you will have to wait and see whether you can qualify or no. Also a student from Kerala usually gets a 5% relaxation from the cutoff mark if he is not from the elite class. 

Good luck
