Princeton Laboratory Learning Program: What is it like?

Hi! I was wondering if anyone has attended this program. If so, what did you think of the program? Were you able to present the research at a fair like Intel or Siemens? Does attending this free program also seem better than other paid programs like Garcia and SURF programs? And is this program helpful towards admission to Princeton? Thanks!

I applied also…anyone have any ideas?

What is the SURF program?
