var1979, I'd heartily recommend Schaum's Outlines, as they have tonnes of examples and worked problems. I would also recommend a book called 'How To Think Like A Mathematician' by Kevin Houston. I know you can get cheap editions of books over there, and I'd really recommend this as an alternative to distance learning. Check out the major UK mathematics departments for tests and lecture notes to consolidate what you learn from the books. I suspect that trying to learn everything online will be much more difficult, and you won't get to enjoy the wonderful weather or cafes, which are the perks of learning Maths! The only thing is: give yourself targets, rewards, and plan your study as though you were studying for exams. As an additional layer, try coding the stuff for fun, especially linear algebra, discrete mathematics and numerical methods. Once you're confident enough, go back to the unis and tell them you're happy to take a test as you've been preparing. Just make sure you've covered the exam material on the university websites first. Its tough but if you're committed then you can do it.
