I did 3 electives in path this summer, and they were pretty laid back. I would say to use it more as an experience to help you decide what type of program you are looking for/see if that program would be a good fit for you. If there is a particular area of pathology that you want to spend more time in, let them know ahead of time, and the department will most likely try to schedule it for you.
If you are trying to get letters of recommendation, I would suggest trying to get to know one or two of the attendings well, and then asking them towards the end. Most places have you do a presentation to the department, which is pretty much what your evaluation is based on. I used the presentations as opportunities to work more with certain pathologists, which can help you get a letter as well.
Other than that, just relax and have fun. It is a great opportunity to see more of the country, and meet new people. Oh, and don't be weird towards the residents because they have input as to what they think of applicants, so just don't be a weirdo and you should be fine. 🙂 Best of Luck!!
