You might want to try the Larson 8th ed or the Finney books. Much more "user friendly" [than Foerster] so to speak. I use Larson in my AP Calc (both AB and BC) but supplement from several others. Foerster has a supplement that goes with it called calculus explorations (and one for precal also) that are excellent.
