consult halliday resnick book. You dont have to go through the whole book. Just download the syllabus and past papers and study topic wise. Remember you will never find all the content of the syllabus in one book. For example the lorrentz transformation derivation, compton and shrodinger wave equation and similar kind of derivations you will get these through the internet only. Similarly michelson morley expirement in relativity chapter, you will find it out by an Indian authored book. I dont remember the name. and another very important information for you, its course content is quite lengthy. You will have to spare a month for only this subject with full dedication. If you have the aptitude only then go for it. otherwise it is not easy to carry this subject.

Fsc physics and chemsitry books also need to be consulted. Like atomic, nuclear and electronics portion, fsc physics and chemistry books will be enough.
