My dd is concerned about the teachers she wants to write her letters. She has had a great relationship with her AP chem teacher from 9th grade and her AP bio teacher from 10th. But she's been hearing that she ought to have teachers from 11th or 12th grade writing her recommendations. Is it better to have more recent teachers write her letters? What difference does 1-2 years make? She continues on as a TA and tutor for both classes, so she has some continued contact with these teachers, though it is online, so not very directly.
Thank you for sharing your experiences and suggestions.
