My Junior’s score went up 90 points. 97/99 to 99/99. SI increased 16 points. He did SAT/ACT prep in the summer, finished those tests in Sept and ended with the PSAT. He worked with a tutor and nearly all of his improvement was in reading. For those parents with STEM kids that trip up on the reading, I strongly recommend a personal tutor. Those kids don’t have trouble with reading as a skill, they just need some pointers on how to take that particular section of the test.
