I think everyone's actual situation is different, so it's different, because some people study efficiently in the morning, while others study efficiently at noon or at night. It's mainly up to you. You should first find a time when your study efficiency is relatively high, at which time you have the worst subject, and then find some time to study other subjects. I think if you are efficient in the morning, you should go to bed early at night and study more in the morning. If you are efficient at noon, get up late in the morning, go to bed early at night, and make up all the sleep during your study time at noon. If you study efficiently at night, you must get enough sleep at noon. Adequate sleep is good for your study, which can make you energetic and improve your study efficiency. Then remember, when you are tired, you should hurry slowly and go out for fun. Don't study hard, it will reduce your study. . I also want to tell you how to study: just buy a notebook for math and English (hard cover, easy to keep, very useful when reviewing in the future), and write down the key points, concepts and expanded knowledge that the teacher said in the textbook, and then you need to prepare another notebook for math, that is, write down your mistakes, some of which are due to carelessness, miscalculation and so on, and you don't need to remember. Then write down the correct method. You can understand it by asking others, which will be of great use in the future. English notebooks are good for memorizing grammar, sentence patterns and so on. Then you should buy a word accumulation book, thick and hard. On the one hand, you should write down the necessary words, and also write down some extended words that the teacher said in class.
