Hello I'm a 2018 hopeful. I was wondering, what can I be doing to better my chances of getting into the candidate phase? I graduated high school in 2011, and am currently taking summer courses at my Penn State satellite campus. Also, I've already begun finding people to write Letters of Recommendation (LORs) for me. I know there is no equation or single answer, but what are "they" looking for in an LOR, and who are good examples of recommendations that carry weight?
