How to keep an A in Math?

@gettingschooled the EC was a competition that only goes up to 8th grade so she won’t be doing it next year @mathprof63 Thanks for the advice about the AoPS book. Do you know any resource that is a physical textbook and has problems to solve?
@bjkmom Thanks for the wealth of information! We will definitely go through those topics.

Since Intermediate Algebra AoPS (just the textbook) is considered to be too advanced to practice for Algebra 2 (she would also be doing these problems throughout the year as necessary), does anyone know the appropriate AoPS level or any other textbook or workbook that she could throughout the school year just for extra practice?

Thanks!

ETA:
The AoPS was recommended because of its conversational tone, does anyone have any other recommendations for workbooks or books for math other than textbooks?
