If me and you have a wrestling match, and then a swimming competition as part of our Biathlon, I believe you would not like being awarded for the swimming competition based on how well you did in your wrestling match. Internationally it is not acceptable. The impact from a particular sport should come implicitly based on the difference in performance in that particular sport, and not externally forced. A 2% difference in Board exams is a 2% difference in Board exams and should be differentiated accordingly. But I have gone ahead and assumed you would not like such a thing. Would you? I leave that question open to you. -kshitij 8879335165
