Yes, if you supplement it with problems -- you'll have to find them elsewhere or make some up yourself. (There's a companion book of exercises recently published, not on the website, which I haven't read.) Of course different books help most for different people. This one's not the best if you want to pass a course and put it behind you. I think it's very much worth checking out if you want to be challenged and inspired to tackle problems for yourself and perhaps pick up a bit of how Feynman thought. There are very few other introductory texts by physicists of his stature: Matter and Motion by Maxwell, and, well, anything else? (Not counting popularizations; it's a fuzzy distinction, but these are securely on the textbook side.)
