Someone wrote in early March and didn't provide their name nor email address. So sadly, I cannot answer their question. 🙁

I'll post it here though in case, by chance, they will read it.

In the summer of 2020 I read much about your program and decided to put all of my children in your program for the 20/21 school year. I understand about the placement tests and used those to decide what would be best for each child. We used a recommended program for several years that I believe really stunted my children’s growth in learning math. That combined with some major illnesses in our family, we are very far behind in math. Most important on my list is my 11th grader who struggles more with math anyway. There were some things as far back as the third grade book A that she did not fully understand. We started there with her and let her go through the book quickly spending more time with those things that had not yet been learned like area and perimeter among other things. She seems to be grasping this foundational work quite well. My question is would you recommend she continue through the books in this way or should we reassess and maybe skip a couple or few books? I am very sad my children did not start with this program from the beginning. My fourth grader, sixth grader, and seventh grader are breezing through and catching right up quickly. But with having only one more year with my eleventh grader, I want to make sure she gets everything she needs. Thank you for your help.

I suggest to use the placement tests as ASSESSMENT tests, to find out what topics she would need to study.

At this point, with only one year left, I suggest to focus on these topics first of all: fractions, decimals, a bit of ratios, and percent. That is because those are the most important topics related to real life. Then as time allows, you could also try cover statistical graphs, some geometry, proportions, integers, etc., using your judgment.
