My son is appearing for his class XII with commerce. He has the following problem when he prepares for the exam.
He feels he knows everything but when he sits for exam sometimes he cannot recollect, make silly mistakes and also at times does not understand the question.
Chant “MUSTARD, DIAMOND” over a glass of water and ask him to take it on the date of exam.
Write “398” in a paper and keep it under his pillow.
Recollect from memory: DIAMOND
