Extended reading: how to review the adult college entrance examination 1? Be familiar with the test questions and arrange the test time reasonably.
You should clarify or clarify several questions: the exam * * *, the total score, and the subjective questions such as multiple-choice questions and fill-in-the-blank questions. In this way, we can allocate the examination time reasonably in the examination, and we must avoid wasting a lot of time in unworthy places and affecting the answers to other questions.
Generally speaking, fill-in-the-blank multiple-choice questions should not exceed 40 minutes at the latest. You must set aside an hour or more to deal with the big problems behind, because big problems mean that you should not only think, but also write.
2. Clever solutions to fill gaps
The scores of multiple-choice questions and fill-in-the-blank questions in math exams are still very high. You don't need to answer this kind of question, you just need to answer it, so sometimes you should pay attention to skills. For example, the clever methods commonly used in choosing fill-in-the-blank questions are: exclusion, combination of numbers and shapes, drawing observation, substitution verification and so on.
These skills and methods are also very important for us to choose fill-in-the-blank questions in the usual topic explanation, not only because of the scores, but also because they will directly affect the candidates' mood in the exam and often become the key to the success or failure of an exam.
Learn to choose.
When taking the exam, you must choose according to your own situation, which can save time and improve accuracy.
Try to spend more time on the first few questions of the big topic, and don't lose points on the topics you can do. The last two questions of the big topic, ask as many as possible. Students with average level should first do what they can in the fill-in-the-blank multiple-choice questions. For big questions, write as many questions as you can. If it is too difficult to finish the last two finale questions, it is suggested to give up boldly and take the time to check the questions that have been completed before to improve the accuracy.
You should remember the basic mathematical formula.
Basic mathematical formulas must be learned, such as power function, exponential function, logarithmic function, trigonometric function, inverse trigonometric function, calculus formula and so on. Some mathematical formulas are similar and easy to remember, so we should also master the methods in the process of memory. If it really doesn't work, use formulas and do more exercises, so that you can quickly understand the application and connotation of formulas.
