Dear Irshad, 

Based on the previous years trends of Kerala Engineering Architecture Medical(KEAM) exam, the closing rank for Btech. in Computer Science for government college is around 55000.

So, considering your rank as 15000, you have a very good chance of admission.

Commissioner Of Entrance Examinations(CEE), Kerala will be conducting the online counselling of KEAM 2019 from the fourth week of June
