Hi all, I am in the process of applying for a few REU programs for this upcoming summer. Right now i am facing difficulties compiling the letter of interest. So, i thought someone here, who has enough experience, might point me to the right direction in terms of what are some of the most important things to be included and what would make no difference. In other words, how should i start writting it? By saying what things first and save what for later? Where should i focus more, what points need to be more elaborated and others slightly touched upon? I understand these are a lot of questions, but i would really appreciate if you could be of any help. Thanks a lot in advance!
