I took it this sophomore year with absolutely no prep classes and it showed my strengths and weaknesses to the extreme. The test itself isn't difficult unless you are person that becomes stressed under time constraints. Now I know what I should work on in preparation for the next PSAT, and finally the SAT itself. The purpose is not do well, just prepare you for the SAT so I do not believe the difficulty of the test should be of much concern. Hope I helped and good luck!
