Hello Jay

No medical college will allow leave for 5 months.

As you are first year MBBS student you must be well aware of 75% attendance rule.

Basically required attendance is 80% and there is 5 % relaxation.

This rule is strictly followed , In case of genuine reason sometimes students are allowed to give supplementary exams which are held around a month or two later the main exams .

If you are struggling with your illness, its better  You can go to talk to your Dean.
