What is the psat test?

The PSAT test is the qualifying exam for the National Merit Scholarship competition. It's given during your junior year. If your test scores are among the highest in your state, it can qualify you for merit scholarship aid from a number of schools, as well as help you get admitted to the top schools. I don't know if there are study aids available for the test, but I would guess there are since it's such a major test. (Check at Barnes & Noble or Borders or Amazon.com to see if there's a prep book or prep software available.) Your SAT scores are the ones that really count for college, but being a National Merit finalist looks good on your college applications and can put money in your pocket, too. I think becoming a finalist also requires a certain amount of extracurricular involvement, so check into that, too.
