This varies from person to person. If you feel stressed before the college entrance examination, listening to some light music can make you relax, thus reducing the pressure. But if you feel calm at that time and can face the college entrance examination calmly, then I think it is unnecessary, which may have a negative impact. Keeping your brain immersed in music will only have a negative impact on solving problems, so I will give you a suggestion. It is to quickly adjust yourself to the best state according to your wishes at that time and your usual habits. Whether to listen to music depends on your thoughts at that time. If you want to listen, you must choose music that you like and can make you relax. I wish you good results in the college entrance examination!
