Introductory books with lots of problems

[h00zah]

Are there any good books that focus on teaching the subject then supplying many problems? For trig, algebra, geometry and calculus at highschool (gr 12) -> first year university levels. Basically refresher books that will help bridge the gap nicely for going from highschool to university.

"Shaum's outlines" are available in any book store and, while not great for beginning study and low on theory, have many examples and problems.
