I remember when I was in the college entrance examination, my family asked me to hold incense, and then I went to a very high temple to burn incense. In fact, I didn't believe in these ghosts and gods at that time, but my family really wanted to let me go, so I didn't want to quarrel with them at that time, so I took incense and burned it in the temple. Then I remembered that I had taken three extra-long incense sticks, perhaps more than one or two meters high, and then I went to worship with that incense stick, and I felt that I met many people for the college entrance examination, so I didn't feel anything wrong.
I think you actually give yourself some comfort by worshipping God and Buddha. You think you are blessed by the gods, and then you will play better, because some people may be in the college entrance examination, so I feel particularly nervous. But if you worship God, you will feel that God is protecting you, and you will feel that you may be no different from the usual exam. I will definitely play my normal level.
In fact, I don't think it's a bad thing to worship Buddha, because he may say that you can ease the tension. But if you don't study at ordinary times and place your hopes on worshipping Buddha two days before the college entrance examination, then I think you can get into college by worshipping Buddha without studying. Then I think you are wrong, because no one can succeed without hard work, so I think if you don't study hard, try not to worship Buddha for any psychological comfort.
