<p>How do you go about getting rec letters from these types of classes?</p>
<p>I heard the TA often writes the letter and the professor then signs them.</p>
<p>By getting to know the professor. Be persistent, but not overbearing. I personally would never used a TA LOR. I prefer my letter writers to have PhDs (or some doctorate degree).</p>
<p>How do you set the deadline for the letter to be written? I’m not applying for another 1-2 years.</p>
<p>I know professors are insanely busy and they often have problems with getting letters written in a timely fashion.</p>

<p>Ask now! Don’t be the person that comes in during their third year and says “um, yeah I took your class 2 years ago - can I have a LOR?” If you did well in a class or got to know the prof and want a LOR from them, go to the professor the next quarter. That way you don’t have to worry about time, etc.</p>
