Question about recommendation

<p>I also am applying to MIT.I put chem teacher and wind-ensemble teacher.
I read the post, and I am very confident that I did very well in all classes. Such a great post!
But whether the writer is good or bad at grammar or not seems to be really important.
What if my chem teacher had awful grammar or lame skill in writing.Ah then it will be horrible!
I guess I will go with 2.
Also, if there is optional recom from employer(in my case, director of volunteer), it’s not really necessary, right?</p>
