I have less attendance in my dadh practicals and theory, and in physiology both theory and practicals.

So..I'm a first year BDS student and i had health issues this year i couldn't balance my bds curriculum.
My dadh practicals percentage is 31% and theory is 58%

They have told about physiology about ik for sure that's lesser too.

I wanna know how supplementary exams work and I'm scared that i have to repeat a year...
