I have been a high school math teacher for four years, and I have met students like you. I'm not totally against what you did, because everyone has their own way. I suggest you find out all the math books in high school for three years and read them chapter by chapter. If you can recite the definitions, formulas and examples of each section, your double foundation will be very good. It is important that you know how to apply the definition formula in this section when you recite the examples. From this, you will also apply what you have learned in this section to other topics.

The foundation is not good, so we must make it up. There is no other way. Reciting examples is also the foundation. Only with a foundation can we improve.

It's no use reciting comprehensive questions. Remember, remember! !

My suggestion is for reference only. I hope you work hard and cherish every second!
