Who Should I Ask?

<p>I will be applying to grad schools come this fall, and I'm starting to think about the whole process. I'm wondering who I should ask for my letters. How advisable is it to ask for letters from:</p>

<p>[ul]
[<em>]People I've worked with during summer internships/REUs
[</em>]Professor I've done research with, but who haven't had much input on the project in about a year. This started off as a research project sophmore year, this year he really isn't around much. Our research project now is kind of like a club in that its mostly student run.
[<em>]Professor I TAed for and took a class with sophomore year, but haven't had much academic interaction with otherwise. I know him well in a social context however.
[</em>]Professor I took a few classes with freshman and sophomore year and with whom I am currently pursuing an independent project, in addition to another student (we meet weekly to go over our progress, and he provides input and suggestions).
[/ul]</p>

<p>And as a general question, is it common for UG research advisors to not meet very often with their students (~1/2 - 1 hours weekly)? Or am I worrying about nothing?</p>

<p>Thanks!</p>

<p>Some of the people I worked for I didn’t even meet with once a week.</p>

<p>I’d say all of them look like pretty good options, though the worst is probably the one you TAed for. You want professors that can write about your ability to solve problems, work ethic, and overall research ability.</p>
