If you don't know anything in the book before, don't do the problem. You should understand this book and the questions behind it this month. You should be able to understand any question and know what it will test you. You may think that books are not important, but the most important thing is textbooks. You should try to remember what each chapter of each math book is about with your eyes closed, so that you won't panic when you meet a question in the college entrance examination and know its source and test site.
If you have listened carefully in class before and your knowledge is clear, what you have to do this month is to do as many questions as possible! Of course, doing problems is stressful. You can spend a few days studying topics that you seem to understand. In addition, make sure to do at least one set of simulation questions within the specified time every day. If you take a math test at 8: 00 a.m. 10 in the NMET, you should do a set of simulation questions similar to NMET at 8: 00 a.m. 10 every day. Also, when doing science questions, you must not just look at the questions and think you can't and then look at the answers. It's futile to do so many questions, so you must think!
Finally, it is also the most important, the most important thing: we must put our minds right! Try your best and don't regret it! As long as you work hard and struggle wholeheartedly, that's enough! Maybe your teacher will tell you how important the college entrance examination is, it is really important, but it is not the only turning point in life. While paying attention, try to look down and keep a good attitude!
I said so much nonsense, not for your grades, but as a person who has been through it, when I saw the word "college entrance examination", I couldn't help but think of my depression and confusion in those years, and I felt it. I hope I can help you.
Good luck!
