If you didn't do well in the senior three comprehensive test paper, there must be a reason, because there is some common sense in the comprehensive test paper at this time, so there must be a reason for your unsatisfactory grades. As long as you find the reason, your grades will not be affected. For example, if you don't know probability, then learn more probability, if you don't know geometry, then learn more geometry. If you understand all this, if it is because of time, then you should strengthen training, so as to improve your grades and there will be no troubles.
