If you like videos,
Khan Academy is great.
If you're looking for an entire course equivalent,
MIT OpenCourseWare,
edX, and
Coursera all have courses (but under different names). Many are archived / self-paced so you could go in and just get the content for the sections that you like. I they're all a mix of videos, typed examples, and practice questions.
If you prefer just reading, there's
Physics Classroom (I personally find it confusing, but it's easier to understand than most.
Spark Notes can be very test specific, but it might still be useful.
