Letter of recommendation question

<p>After reading that it is "pretty standard among selective institutions" to "like to hear from a math/science as well as a humanities/social science teacher" in recommendation letters on a UChicago blog, I have some questions.
1. I have good personal relationships with all 3 of my teachers who are writing letters for me. I'm also involved in the math club, which my math teacher heads, and the swim team, which my English teacher heads. My math teacher taught me in Trigonometry / Analytic Geometry (freshman year) and BC Calculus junior year. My physics teacher taught me in AP C Physics junior year. In all 3 of the math/science classes, I was with mostly students a year older than me, and I did very well in those classes. My English teacher taught me Film Lit (semester elective) junior year and is currently teaching me in English Masters Honors senior year. I've done reasonably well in both of these classes 2 (A's, but not that solidly and with a good deal of effort in English H). Should I submit 2 or 3 letters in this case?</p>

<li>Would you say the UChicago blogger is actually accurate here?</li>

<p>I doubt it matters unless you want to go into engineering. I had my AP Span Lang teacher and my AP Lang and Comp teacher write my recs, and I heard they were both phenomenal even though I didn't read them.</p>

<p>Don't submit 3 teacher recs. 2 teacher recs and 1 additional from maybe a coach, boss, etc.</p>

<p>P.S. I got into UChicago with those recs.</p>
