Jeffrey, the benefits of the College Prep Scholarship are listed here: College Prep Scholarship Overview
I was a recipient of the college prep conference and nomination for a college visit. Going to the College Prep Conference really impacted me. I learned so much about the opportunities for low-income students and how financially possible it is for us to be able to afford an education from some of the nation's best colleges. I made friends that I still keep in contact with and I met with many admissions counselors. There were so many other things I've gained from that experience but I'll leave what I have listed so far as the major advantages. In my year, there were college prep conferences at Stanford and Yale. For yours, I believe they are at Stanford, Northwestern, and Princeton. QB also gives out a few travel stipends for students to attend.
I'm glad to see your enthusiasm for applying with all your questions and your eagerness to fill out the Match Program application.
I believe that the Quest for Excellence awards are only part of the junior College Prep Scholarship.
Feel free to let me know if you have any other questions.
