Why are OpenStax’s sections not matching up with the content in Expert TA? I thought my textbook was mapped so they would match?

Expert TA is easy to use, provides great value, and gets the job done at a better price; it really does a good job. The problems are a cut above what I have seen in other web-based homework. They are more complex and detailed. They have more different parts and each one of the problems addresses another aspect of physics.

I went with Expert TA because I had been using a publisher’s system and all of the answers to all of the questions were available on Google.
