well lets face it, we don't really know what they write in our LOR unless you don't waive your right. So is there way to tell that your professor would at least spend some time to write some good letter? My professors said they are pleased to do write the letter for me and they actually ask me to keep them updated if I get in or not. I do have good relationship with them and did well in their class. So what are the chances that they will actully write a letter that is longer than like ten sentences? I mean a good letter.
