I've heard that when it comes to rec letters, optimal is 3 science and 2 non-science. What I'm confused about is whether these have to come from professors, as in 3 science professors and 2 non-science professors, or if they can come from other areas fulfilling those areas... for example 2 sciences coming from my research lab and my clinic and then 1 from my youth group. Thanks for the help if you respond. 
I had letters from 2 science professors, my leadership studies advisor, my boss (I worked as an RA in the dorms for 3 years), and a physician I had spent a lot of time shadowing. I think it's better to get letters from a variety of people rather than just professors. It shows you have interests and responsibilities outside of school.jnguyen0815 said:
other assortments of LOR's are perfectly fine, but i would suggest getting at least 1 letter from a science prof who knows you in a classroom/academic setting to guage that particular set of abilities. although, i wouldn't say this is a deal-breaker, either.jnguyen0815 said:What I'm confused about is whether these have to come from professors, as in 3 science professors and 2 non-science professors, or if they can come from other areas fulfilling those areas... for example 2 sciences coming from my research lab and my clinic and then 1 from my youth group.
