im interested in both but im just wondering because im getting them for both Asset and my self. Which one is better for high school?
bond
Not sure about high school and I never tried p90, but p93 is very good and perhaps the best putative I have yet used 
.
It gives some consistent results and there are no negative hit 
that I can attribute to p93.
There is a little more about it in my signature link about putatives
