Forget Bond. You need to be doing GL Maths papers and CGP and First past the post CEM Papers but only the English VR questions.
Letts 11+ books are also pretty good (but less challenging than First Past The Post if you need to build up to something harder) and they do CEM-format 11+ practice papers. They must be quite new, I didn't see them last year.
Agree re. Bond in principle but they have also recently published CEM-style practice books. Those that are CEM-style, have it clearly stated on the cover.
DG, when you said 'forget Bond', did you mean their 'old style' practice books/test papers or the CEM ones? We didn't use their CEM books so I don't know how useful they may be.
