Letters of Recommendation from Core Subject Teachers Only??

We were at an information session last week and the admissions representative said that they prefer letters from core subject teachers. My D would like to ask her Latin teacher and Computer Science teacher because they know her best. She could ask her history teacher (instead of computer science), but she doesn’t know her as well. What would you advise?

Thanks for your help!

It’s hard to say, but I think sending in a bad LOR from a core teacher is worse than the opposite. I would ask the CS teacher.
