Pay attention to answering skills. The general practice is to make it easy first and then difficult, pay attention to the accumulation of minor problems and enhance confidence. We should think flexibly, pay attention to multi-angle thinking, and overcome difficulties flexibly from different aspects. If you can't answer the question at the moment, just put it aside and come back to continue answering after answering other questions; Inspired by the process of answering other questions, it is likely to be suddenly enlightened, break through and be solved. Questions that cannot be answered should be given up decisively to prevent taking up too much time, affecting the completion or review of the test paper, resulting in no time to answer easy questions, and mistakes and omissions in the test paper cannot be corrected in time.
