So it's not too hard for them where you're not overloading it.

A classic one on this one is fluency.

which is fluency.

You can solve harder math problems if you know your multiplication tables and division tables.

And so for students who are struggling in advanced math, part of the problem is just go memorize your multiplication tables, which they all can do.

And then all of a sudden, their higher level math scores get better.

We have one student who was, this is sort of a unique and extreme example, and I hesitate to say it, but we had a student who was 740 on the math SAT.

And in looking, they were making careless errors.

Some of the problems they were overloading work and memory.

And for whatever reason, the student didn't have fluency of multiplication and division tables.

So we literally sent her back to third grade math.

We're the only school in the world who will take a 740 math SAT student.

Back to third grade.

Send back.

And she got a 790.

A 790.

And it's that kind of thing where when you talk about the science of learning and just, I say it this way, the parent and the student in this case were not excited that their 740 math student is being given third grade problems.

That can't be the issue.

But it is.

It is because you're overloading the working memory and she's just making careless mistakes.
