Hi Rahul, the cutoff varies every year based on various factors like number of seats available and category etc. However one need to have a minimum cutoff of above 60% in the hsc examination. But the candidates need to score more than 70-80% in the field of interest, like here you need to have above 80% in Physics in HSC exams. The cutoff varies around 70-80 and a score above 80 is a safe zone.
