Hi there,

Passing marks for cbse 12th class board examination is 33%. As total marks for theory exam for term 1 exam is 40 then students should get 13 marks to get pass in examination. But students should try to get more than 20 marks to get better aggregate.

In case students must score 33% in theory and practical to be pass in each subject.

Furthermore,students need to score 33% separately in practical and theory.

If you score 33% separately in practical and theory then you will be pass in 12th.

Hope it helps you

Good luck!
