How could i tell my father that i have 3 more remaining subjects in my college degree?

My father knew that i have no more remaining subjects in college. But i am afraid to tell my father that i have 3 more subjects to go because he's so strict. Our school started its class 2 days ago. I need to enroll those 3 subjects so that i could finish my degree. the another bad side is i don't want to give burden to my father the down payment for the enrollment is 16k.
