Outside of the United States, there are test standards called the GC(S)E "A" and "O" levels which are roughly equivalent to entrance exams for college/senior high respectively. Because these exams have been going on for DECADES, the examining body has basically given up on guarding these questions i.e. they are regarded to be in the "public domain". Enterprising publishers have called these collections of questions the "10 year series", which are exam questions from the previous decade. There is not a single person in this part of the world who does not own a copy when preparing for those exams.
