There are many careers out in the big wide world.  Young folk entering upper school who want to be a solicitor or barrister, or even a court judge, will need to have a pretty good idea of how to go about it before they select their subject route.  They will need to choose the right ones needed for law – the top schools already know this from centuries of providing the type of student.  The state schools who now produce equally brilliant students have also started to up their game and ensure the careers advice and coaching is adequate and effective.  Once the subject choices are made, its rather disruptive for the student to change part way through and wastes a lot of their time if the wrong advice or information has been provided.  The exam grades in those subjects will also have to be absolutely top notch as the entry process for law school or to get a law degree at university is dauntingly pressurised as there are always far more candidates than places.  But hard work, self confidence and knowing what one wants in life are talents to be honed early on!
