1) I went on the NSF REU site and looked through the ones for engineering, but it appears many, if not most of the sites have not updated their page from the past summer. It's already november and most deadlines are due in february. Anyone know when they usually update their site?
2) As seen in the above website, a lot of the potential sites do not have any links to click on the left hand side. For example, in the first row, there's no link to "Cornell University-Endowed REU-Site Program at the Center for Nanoscale Systems" application site or anything.
3) How long should I give my LOR writers to write the letter and submit it?
4) I'm currently a junior. I'm pretty sure I know what research area I want to pursue for grad school. Should I still apply for REUs that are not related to my potential research area?
