Regarding donating to CFAR, I have never donated because of potential benefits for myself, but rather because I want CFAR to exist and do what they do - create new rationality strategies and spread them to the people who attend their workshops. I think the people who attend their workshops have the potential to do a lot of good in the world, and the nonprofit part of CFAR's mission is to give discounts to people who they think will do particularly good things.

Regarding studying past materials, from my personal experience attending a workshop, it just doesn't compare to the real thing.

Regarding whether you deserve a scholarship, that's more up to CFAR staff to determine than you or I :-)
