I live near the NYC area and am pretty experienced with PR. A couple questions:
1) I predominantly use rapid reading, and though I'm experienced with SR+Dip, I'm much more confident with RR just because the type of content I need to know requires it. Are you looking for SR+Dippers over Rapid Readers, or will either suffice?
2) Is this a paid study?
3) Are you able to describe or at least summarize what the testing consists of?
Thanks a lot
