But if you are thinking of applying to 20+ schools it can be a pain for everyone who is curious to look through each secondary, especially when you don't know which ones you will get. Also, I got some messages about schools accepting research profs in place of science profs - so I was a little unclear about that.
Thought having a clear answer to the recommendation issue would be a good resource for others as well as myself...
Well, I will try to give you as clear of an answer as possible as it was in my experience.
Generally, 2 science professors and 1 non-science professor is good enough. If your major is a science major, you should get one from a professor in your major, one from another science, and a non-science. The reason is some schools specifically say one from your major, while most say 2 sci and 1 non-sci.
Both NYMC and Albert Einstein required a letter from my major. My major was biology but I had two chemistry professor letters so they spefically said my application wouldn't be reviewed unless I got the letters. I ended up not sending in my secondaries and wasted $60 on the primary apps for both.
I had 2 chem professors, an english professor, a physician letter, and an employer letter. I sent all those into most schools and it was fine besides the two schools I mentioned. Even Jefferson had some funky requirement of one physics, one chemistry, and one bio but if you wrote them a letter telling why you couldn't get the required letters it was fine.
As far as getting your research one, it will be ok for most schools. However, some schools specifically say two science LORs from professors who taught you. In that case your letter may not meet the requirement.
The safe thing to do is to get 2 sci (one from your major), 1 non sci, and your research professor one. I would say those 4 will definitely get you passed all the requirements for every MD school.
