Hey, guys! I know that at many colleges, they specify that recommendations should be from 11th or 12th grade teachers. For Harvard, though, I couldn't find information about what they prefer anywhere--which leads to my question. For my second recommendation, I have two options: a letter from a teacher I've had in 11th and 12th grade which is probably very good but which is also probably slightly similar to my first letter, or a letter from a teacher who taught me in middle school but who've I've worked with every year since then on my biggest extracurricular, which is probably excellent and leadership-focused. Which would be better to include? Does Harvard allow/encourage additional letters of recommendation? I'm sorry if these are all silly questions, but I couldn't find them anywhere! Thank you all so much in advance
