I presume you don't mean GCSE maths and physics. Most of the good bookshops do stuff on study skills. I think you can find it in the section to do with business / cv/ interview skills. There are quite a few books that give you tips on how to study, how to revise, how to commit things to memory etc... So sorry but can't remember any titles of the top of my head. Also I think either OAA or Cabair do a sort of pre-course for pilots - check their websites. I'm sure someone out there knows of this.
Hope that helps
