There's no essay on this PSAT, but there IS one of the New SAT, so if you're a junior or younger the SAT will have an essay. i still have to write one on Wednesday even though it won't count so teachers can grade it to give us an idea of what our score would be like.
And yeah, sometimes you do have to take tests to get into high schools. My school is a govenors school (I have NO idea what that means) and so I had to take a test and fill out an application. It was worth it though, I love my school.
Keep the peace, take care of each other, and may you find your promised land.
