Sorry, Hilde it is a bit specialised, PPE is an acronym for "Politics, Philosophy and Economics" which is degree programme run by a few notable universities here (Oxford, LSE - (London School of Economics). Since Adam did these subjects at A level and enjoyed them as well as excelling it seemed like a good option and he could have still done law just taking an extra year postgrad. But he decided he did n't want to take the extra time and now he is so bored that he spends as much time as posssible doing stuff with the University Naval Reserve and may well sign up for at least a short service commission .. if he does that his Law degree is likely to "die" for the purpose of Law Society Exemptions and so he could end up doing the extra year anyway ... so he might as well have done subject she liked in the first place
. A lot depends on whether his desire to make a lot of money wins out over his love of reaching the top of a structured hierarchy... he is such a Capricorn....
