Getting a lot of these at work from undergraduates. Often I don’t know them well but they need letters and apparently have no other options. I try to urge them to use better options (professors who know them better) and sometimes that works. But sometimes I have to write a not very supportive letter even though I say nothing negative. I just don’t know them and good performance in a large intro course doesn’t mean that much.
