Hey, he wanted something that would look good on a cv. A degree cuts no ice, nor does a mechanic licence unless he actually wants to be one.
Given that he is still on his PPL, there's not much else he can usefully do that employers want - he cannot sign on to a professional course until he completes it. A language is a cheap upgrade for a low hours pilot - and ICAO doesn't come into it if you are talking to customers.
