High all... I'm currently studying http://www3.open.ac.uk/courses/bin/p12.dll?C01MST209" [Broken] mostly as revision (I have a degree in electronics). I like the teaching materials because they have plenty of worked examples, many problems and, above all, worked solutions to all the problems. I like this as it gives confidence when you can check your answers against a 'good' example. Also, if something doesn't quite 'go in' you can use the first few as additional worked examples. Does anyone know of any books on GR and/or QM that have a similar approach? I've got d'Inverno but there are few examples, many of the problems have no solutions and those that do often lack working.
