First of all, from the psychological point of view: make up your mind, strengthen your faith, eliminate distractions and strive for victory.
Secondly, on the whole: step by step, slow and steady, step by step, and consolidate the results.
Secondly, from the point of practice, it is better to do ten questions than to do one question, and it is better to read ten books than to see through a book. When I was in junior high school, I didn't do well in the exam either, and I often participated in various cram schools. My studies didn't change until I downloaded a course to develop my brain. By learning Tesla brain training, my heart became very calm, and my memory, understanding and imagination were improved. I have mastered the skills of using my brain efficiently. From then on, I stopped attending the teacher's cram school, and all the knowledge was basically obtained through self-study. Self-study knowledge of various subjects easily, and at the same time, I can achieve the effect of applying what I have learned, and my academic performance has advanced by leaps and bounds, and I was finally admitted to Sun Yat-sen University. I hope my words can help you. Good luck. Hope to adopt!
