Having completed my CPL in Sept, here is my advice...
PFLs
Steep Turns
Vne dive recovery
Stalls
Instruments (Unusal att and basic intercepting)
Diversions
Circuits
Wobbly prop and bendy gear differences in not done already
Basically you need to practise the same stuff you did for the PPL test but to much tighter limits.
Good luck
