I graduated from senior three this year, and my math is poor. I think there will be fear in the exam. Then usually take a set of papers and use the evening self-study time to train regularly and quantitatively or compete with me at the same table. You will have fear. Maybe you don't adapt to the atmosphere created by the exam and are not confident in yourself, so you can always create this atmosphere and force yourself to adapt. I believe it will get better gradually.
