<p>Dont be shy about LORs. It’s part of your professors’/supervisors’ jobs to do this. They’re accustomed to it. </p>
<p>One of my professors already sent out letters for all my 9 schools. I can’t say how good they are, but regardless, writing/sending multiple letters is a lot easier for the professors than we believe.</p>
<p>The only thing I’d caution you about is selecting quality programs that your professor agrees with. For example, I had a safety school on my list that I didn’t really care about and didn’t have the program I wanted to join. When I showed my professor my list he immediately called it out - “XX? that’s kind of an egg school…” I instantly knew I shouldn’t apply there. If I still went ahead and sent him a letter request for that school, it might have raised his eyebrows. I don’t want him to feel like I’m wasting his time by not taking his advice. Anything from a professor like “I didn’t know they had a XX program…” is a red flag. </p>
<p>Remember these professors know the strength of other university programs. If anything, they might be able to help you narrow the list. But I think as long as they don’t say anything negative (like in my case), you’re good for as many as you want.</p>
