We have an exam today, and I have a question that I can't figure out! Why are the big questions behind my math just wrong, while the multiple-choice questions and fill-in-the-blank questions are almost all wrong? ... Generally speaking, no matter what kind of questions, your results are always wrong, so you lost a little more points this time.

Listen to your meaning, you have done a good job in the process of big problems, that is, you have done a good job in thinking. Then I think your calculation is easy to make mistakes, so the result is always wrong, right? I suggest you practice calculation more, and it's good to be skilled.
