Im in my gap year and I know its recommended to have 2 science 1 advisor 1 dentist, how concrete is this? My school didnt really offer advisor or committee letters. I have some science ones from undergrad and am currently taking a couple post bacc classes and will be utilizing them as well for LOR as well. I work in a dental clinic now so I have the dentist one down, but the advisor one, i dont have anything for. Can i replace this with someone else in my life who represents this advisory role? Thanks everyone 🙂
