Hello

The first puc and second puc both topics would be asked

But the exact cut off of 1 and 2 nd varies each year by +or - 5 percent

The avergae weightage is 60+40 .

Ie 60 percent of first year syllabus and 40 percent of second year syllabus this holds good for physics and chemistry but maths and biology some times 50-50 some times 60-40.

Thank you
