I would like DS11 to try to qualify for SET (Study of Exceptional Talent), which requires 700 or above by age 12. Because the College Board is changing the test in a year, I want to have DS take the SAT before then so we now have less time but still almost a year. DS tried College Board's 2014 practice test and it appears that he needs to raise his score by a hundred points. DS has never tried any SAT CR questions prior to this practice test and I am not opposed to a little prep. It appears that speed is an issue and there were some careless errors but DS still only got half of the incorrect/unanswered questions right when I gave it back to him so clearly there is room for growth.

What do you think is the likeliness of a hundred point increase in critical reading by next spring without prep and with some prep? Any suggestions or BTDT experience?
