I'm in grade six, too. My English is good, but my math is still a little weak. Knowledge of mathematics mainly depends on practice. Don't do more exercises, make up more, how can you do it? First of all, the calculation should be serious, and don't lose points on it, which is very inappropriate; Secondly, we should clarify the application of fractions and percentages ... In short, it is most important to practice more questions. I recommend you to be a small champion in Huanggang, a big paper in Huanggang, a complete solution to the teaching materials and a tutorial for success. I have all these. I hope you will make persistent efforts!
