That is the key...the colleges take a lot of time to put together classes, with the full understanding that the students will actually try to learn everything covered.

In my house (using Saxon), anything that they miss in the problems, they watch the Teacher video that explains each problem. If they get any wrong on the test, they repeat the lesson.
I am math illiterate so I can’t help them.
They took the test in the article and got them all right.
