Dear Yash, your final score in these subjects is based on your Theory and Practical exams score. If you have scored 25,27 and 26 in Physics, Chemistry and Biology, to pass in these subjects, you should score the remaining marks in the Theory paper. For example if the pass marks are 50 in each subject, you should score atleast 25, 23 and 24 in Physics, Chemistry and Biology respectively to pass your exams.
