Thank you for providing this! I never was able to find this information! Although looking at this report, my percentile (user-based) is different than the score I achieved shown here. For example, I scored 1110 on the PSAT, which on my report places me in the 95th percentile, yet this report for Spring 2016 reports me at the 97th percentile (all percentiles user-based). Why would that be?
Also, I have heard of ways to convert new SAT scores to pre-1995 SAT scores. Would that be a reliable way to do so? If so, how would that be done?
Finally, regarding your stance on the ACT; it kind of makes sense now, since the average that the ACT board reports (which is 20.8 approximately) would represent the average of people who took the ACT, and not the general population, which IQ tests usually do. Would that be correct?
