This set of pdfs is really good, and I'd use them to complement the textbooks I have. It's not syllabus specific, but the topics it covers are usually very clearly explained.
Other than that, I'd recommend looking into textbooks if you don't already have them. They take a bit of getting used to if you haven't used them before, but if you get a good one it will explain things very clearly (a lot better than a teacher, in quite a few cases).
