I suggest you do an interlibrary loan on the 3 volume programmed course Pre-Calculus Mathematics by Vernon E. Howes, copyright 1967. Furthermore, I suggest again to do an interlibrary loan on the 5 volume A Programmed Course in Calculus. The latter is from the 60's also. Both sets of the books allow you to quickly get up to speed or review forgotten concepts.
