Jazzy,
an exam i found probably one of my easier CPL's!
Most will tell you ECHO is the end of the world- it is not nearly that bad and just takes some dedication and study to master.. once you start to realize things about its characteristics and what's required to get its CG back into the green- things start to fall nicely into place.
Totally agree with the time issue- i just finished in time and had done a fair bit of prep. 2 weeks with moderate study i reckon is a good bet.
Aerodynamics is the hardest CPL by far imho due to the wording- the actual subject content is however interesting and quite relevant
