Hello, how is this for obtaining LORs?
1)Evolution professor and also my research mentor
2)Advanced Cell bio professor and also my research professor
3)Zoology professor
4)Oral surgeon (hopefully)
Those LOEs seem pretty good. Usually the 2 science professor/ 1 dentist combo works well. Some schools may want volunteer letters, religious leaders, or other, but you can always call and ask. They seem flexible.
