<p>Timing of test taking can influence scores. Son got a 35 plus ? on the then new writing test on the ACT spring of junior year in HS, and I have forgotten his SAT I score because he had two 800’s on SAT IIs. He was supposed to study for and retake the Math SAT subject test he didn’t do as well on the fall of senior year but he signed for and retook the SAT I- got a 2400. Would he have gotten a perfect ACT score with repetition the fall of senior year? It wasn’t worth the effort. btw- raw scores do not have to be perfect for top reported scores- unless someone has documented new knowledge, look at the percentiles for the meaning of scores. from recent memory- an 800/800 on the general (not subject tests) GRE could be 99% or 94% depending on if it is the verbal or quantitative score (they do a 990 scoring for the Math subject GRE).</p>
