I still suggest that you finish the homework assigned by the school first. You are only a sophomore, don't be in such a hurry.
In the first year of high school, most math scores of 100 were only 40-50, and the scores of 120 were still 40-50. Of the 760 people, 5600 is normal, and occasionally I got more than 700.
Senior two began to grasp mathematics. I didn't buy any exercises, but I finished my homework carefully. If you can't write math before, skip writing, so that the math time is minimized. I was the first to do my math homework at that time. Unless it is a super difficult topic, I must finish it. I won't ask my classmates or teachers. In addition, I wrote various examples in my notebook and made a set of wrong questions. Even if you don't write homework in other subjects, you should give priority to completing math. . By the next semester of Senior Two, my math has reached the level of middle school, and because of this, my foundation is solid (I am not ready to do difficult problems), so if the exam questions are simple, I will be at the beginning of the paragraph.
Test research is a good book, which can be kept for later use. Now, we should lay a good foundation, and then start the sea tactics, brush the questions, check the leaks and fill the gaps, which will be effective, otherwise, once we do the questions, half of them will not work. Then write a hair = =
1. Grasp the foundation, finish the homework and ask questions frequently.
2. Notebook, wrong problem set (if you want to choose, you won't, if you don't pay attention, don't copy all the mistakes)
3. After the foundation is consolidated, you can brush the questions. Like your book, I prefer Tian Li's 38 sets and the whole volume of the golden examination paper. Writing feels like an exam.
