I've posted here before about how I dislike my physics teacher for various reasons. He ignores kids' questions, and he mostly talks about sports, or makes pop culture references and jokes just to get laughs from the class. No one thinks he is a good teacher, and he focuses more on his football coaching than physics teaching. Also, another problem is I don't have any friends in this class, so I tend to not talk that much. I occasionally answer or ask questions when the teacher does lecture. So, I don't really like him, and although I get good grades and act polite in class, he doesn't know me personally. So the question is, should I ask for a recommendation from someone I don't personally like, and someone that doesn't even know me other than the shy kid that gets good grades in class? The thing is, I already have 2 letters of rec in mind from two different teachers, and I would assume the third should be from my favorite subject, physics. I want to major in physics, too. But, would it be alright to get letters of rec from an English teacher, Math teacher, and Chemistry teacher?
