<p>I have three teachers that I've requested letters of recommendations from. The three teachers include my chemistry teacher, AP Biology teacher, and AP English Lang & Comp teacher. I'm the first person in my family who's going to college here in the States and so I'm very confused about a lot of things!</p>
<p>First, my chemistry teacher taught me during my sophomore year. If the schools I'm applying to do not have requirements as to who writes my letters, do you think it would be okay if he wrote one? My chemistry teacher thought highly of me and was very enthusiastic in accepting my request for a letter. Some of my peers told me that regardless, I shouldn't ask a sophomore teacher but I'm not too sure. If someone could point me in a more certain direction, that would be very helpful.</p>
<p>Secondly, my AP Biology teacher recently sent me an email asking me to give her "stamped and addressed envelopes" as soon as possible. I was really confused by this. I thought colleges now accepeted electronic letters of recommendations? I'm applying to most schools on the Common App and one or two big research universities with their own application. Are there schools that still only accept mailed letters? And if so, do you know if there is an accumulative list of these schools? </p>
<p>Thanks for taking the time to read this!</p>
