No prob. They were mostly western for a while, but now that most colleges will accept them (some will take ACT instead of SAT + SAT IIs for example because they are more subject oriented), some students will take both to find out which they are better at - I have a friend who did pretty badly on the PSAT but very good on the PLAN because she memorizes particular subjects rather than just having general knowledge and problem solving skills.
no subject
Um, yeah. Whatever.
