This text book has many lucid example problems as explained by Burger similar to his videos. It is best for learn by example strudents (which is probably a majority of students). It takes a "Just the Facts Ma'am" approach with little historical background or derivation of the concepts. It covers some advanced topics such as Partial Fractions and Mathematical Induction. It covers Vectors but does not delve into three dimensional vectors. It does not cover Limits but this is covered in AP Calculus AB so not a real ding. It is a good text book.

It contains lots of problems/exercises with some more challenging ones called extensions. It has answers for the odd problems and all the answers for each chapter review problem set. The text is quite complete and could be used standalone or along with the formal Thinkwell course. Since Thinkwell courses are only streamed these days, I would purchase this text used (currently in $20-25 range) for future reference.

IMHO It is not suitable for a future Math major and somewhat marginal for a future Engineer or Physics major.

Some other notes:

For the general exponential function Thinkwell uses y = b^{x }versus y = ab^{x }or f(x) = ab^{x}

Some Algebra 2 books introduce and use it this way. I prefer the second form for Precalc.

Thinkwell text does not derive or otherwise demonstrate with data where the compound interest formula comes from with respect to the simple interest formula versus the Sullivan text or Demana texts.
