Math-U-See PreCalculus

Well taught

This is my first year to use a Math-U-See product. So far, my son (a junior in high school) is enjoying the program. The video is well taught and helpful. I have just one complaint- the instruction book used by the student has all the answers to the assignments and tests. Although I understand that the author wants the students to check their work, I think the test answers should not be at the student's fingertips. I am not always home to monitor his work, so I may need to rip the book in half as a solution.
