Its fair to say that if you learn the PPL theory thoroughly and enthusiastically (ie do more than 'just enough') then you are half way to the ATPLs.
Its easy to just pass. But you are storing up hard work for the future at CPL and ATPL exam level.
Trevor Thom contains 75% of the most useful book stuff that I've ever learnt about aviation. Its all very well banging on about reading 'Handling the big jets' - often as not a read through the slim CAP413 would be of more obvious and useful benefit ;-)
Don't underestimate the importance of the PPL - like a house it is the foundation upon which everything else is built. A gash $3,000 PPL in Hicksville crammed into 3 weeks isn't the best start you your career building project..
Cheers
