hello aspirant,

your question is not clear to us and it seems incomplete, you can complete your question and reply back to us.

however,Double pass in plus one will improve the total result of Higher secondary marks card. But in plus two you have to vet minimum marks for qualifying for higher studies. Because all the institutions check the results of both plus one and plus two . For Physics, Chemistry and Biology, out of 70 marks, a candidate needs to score 23 marks to pass in these papers and in practical exam, out of 30 marks, one needs to score 33% which means 10. A candidate needs to score overall 33% to pass the exam

hope that helps
