amrita ma'am my exam is on wednesday. i wanted to ask that if during the exam i don't get my answer by asking how what should i do in such a situation?

Better not ask maam. She will get angry. Don't worry and don;t become tensed in the hall due to this. Think about what maam taught in the class on that topic. If you don't know I suggest you leave that questain. Then during the last 10-20 minutes try to think again. If you still don't remember, stay cool. Give your Questain paper and once you are out of the hall check the answer. Realize  the mistake and tell your parent/parenyts that you tried. They will understand you. Stand aside and pray to god
