MIT says:
"MIT requires two letters of recommendation from teachers. One recommendation should be from a math or science teacher, and one should be from a humanities, social science, or language teacher, although this is not a hard requirement.
You should ask a teacher who has taught you in an academic class in high school. Ideally, this will also be a teacher who knows you as more than just a student who does well on all the tests. We find that the best recommendations are written by teachers who know an applicant well as both a student and a person."

这又不是研究导师写的额外推荐信,需要大学老师来做。州大和高中老师,别人更相信高中的老师。至少高中老师和你混在一起的时间要比大学老师长,而且高中老师能够有相对的比较。
要搞清这些东西你要么你花钱请申学指导指导你,要么你或你的孩子自己得化时间去看要申请的每个学校网站上的指南,每个学校都会写得很清楚的。到紫檀来问,很多和你一样糊涂的张口就来给你提供议见,这样即使有正确的建议,混在一起你也搞不清到底哪个是正确的, 特别是有些回复,看似春药很有道理其实是毒药。
