The most difficult thing will be getting your math up to speed so you really need to dual track the physics and math. The Landau books are good but assume probably more math than typical college text in mechanics, em, qm, etc. Probably a bit down the road for you if following typical curriculums (perhaps not others) the MIT 80X series by Zwiebach were good.
