In the West Bengal Board of Secondary Education (WBBSE) Higher Secondary (H.S.) exam, Theory subjects typically require 30% to pass , which is usually 24 out of 80 in theory and a total of 30 out of 100 . You scored 24 , which is just at the edge of passing (if 24 is in theory).If practical marks are added and you're above 30/100, you may be considered passed. In maths 60 is a decent score and clearly above the pass mark.40 marks – above the pass mark, but not high which you scored in Biology.

So, conclusion

• If these marks include theory only and your practical/internal assessment marks help you cross the 30/100 threshold in Chemistry and Physics , you may have passed.

• If the marks are total including practicals , then Physics and Chemistry might be a fail if 24 is your total out of 100.
