Hi - I'm doing an honors degree in physics by distance learning, having received my B.Sc around 20 years ago. I find there is a lot that is presented quite differently, and also stuff that I don't remember well enough - or not at all. So I'm looking for the fewest books that I can use to revise modern physics fairly quickly up to post-grad level. These would need to have practice problems etc. - if possible with model answers so I can check what I do. All advice appreciated.
