<p>OP, your comparison is statistically invalid! You are comparing a composite ACT/whole SAT conversion chart to charts giving you percentiles for INDIVIDUAL sections of the SAT. Your math or reading section puts you in the 93% range, but if you are 93% in both, you are much higher than 93% when you combine them. This is because it is much harder to get to the 93%mark in two different test sections rather than just one. Most kids that hit 93% in math WILL NOT hit 93% in reading, and vice versa. The WHOLE TEST percentile comparison between the ACT and SAT will match up with the first conversion charts you link to.</p>
