When I took exams in England (admittedly a decade and a half ago) there were indeed different questions based on what you had learned, but you were instructed to only answer one of them (if you answered more it didn't count), and they were all worth the exact same number of points. It's possible some schools taught two texts to let their students choose whatever was easier on the day, but I doubt this was widespread and I don't see this system as being unfair.
