Just wondering (to give myself some hope), has anyone on here seen a twenty point increase from their diagnostic as a result of intensive study? Specifically from the mid 150's to the mid 170's? If so, any advice?
What is the score difference that would notnall rate an addendum? Is it by tens (“I jumped from 160 to 170 and this is why”) or a certain number of points jump (“I jumped from 152 to 167 and this is why”).
