I need one more science LOR. I am thinking that I can potentially ask the professor of the class I'm currently enrolled in towards the end of the semester. Do you think there would be any way of mentioning to him now that I may ask him for a LOR at the end of the semester and somewhat check to see if he is availbe to write one? LORs are due to my pre-health committee may 30th and the class won't be over till may 4th. So could I potentially ask him for an LOR before the class is over. I'm very worried because I'm not real sure about asking anyone else for an LOR. Also I was wondering can a lab instructor write a science LOR? She teaches many different types of biology labs (I had her for ecology lab) and also teaches an anatomy class. She isn't a Phd though. Would this not be a good LOR to get for the science requirement? Thanks for the help.
