Do not listen to the comments about your scores.
1150 PSAT NMSQT is 87th percentile for 10th graders taking the test not for 8th graders! It is 74th for 11th graders. I can’t even find the percentile for 8th graders, probably because most 8th graders take the PSAT 8/9. An 1150 on the PSAT 8/9 would be 99th percentile. Your score is great no matter which PSAT you took as an 8th grader.
