Pilot 16
Wait until you have received and used the manuals that will be issued by your college for a couple of weeks. Buy Oxford manuals only for the subjects inadequately covered in your issued manuals.
I have heard that some of the Oxford manuals, while no doubt beautifully written, edited and produced, do not cover the whole syllabus. I do not know whether this is true, but this is another reason why you should not buy Oxford manuals until you have something to compare them with.
Best regards,
