First of all, you should have your own small plan and goals, such as which knowledge points I want to learn well today, how many words I want to recite today, what effect I want to achieve in a week, and how many mathematical formulas I want to recite. If you can't master it well, you will have to pay more attention. I don't know how you master the cultural knowledge of primary and junior high schools now. If it is good, it is necessary to learn the following knowledge. If you forget, you will have to pay.
Secondly, you said that you should continue to study at this age, and I definitely support you. In today's society, you just have one more choice than others. Knowledge can not only enrich your brain, but also enrich your life and increase your confidence.
In the end, I may only give you this knowledge about learning, and nothing else can help you. At the beginning, you may be more painful and suffering, but you must stick to it, so that you will get a pleasant surprise. Finally, I thought of a famous saying: "Birds want to fly first, and people want to be advanced." -Li Kuchan ".
