My left margin is greater than my right. I've not made any explicit changes to margin sizing. I'm compiling with Texmaker to PDF. I'm using the following packages.
\documentclass [MS] {uclathes}
\usepackage{chngcntr}
\usepackage{graphicx}
\usepackage{amsmath}
\usepackage{url}
\usepackage{listings}
\usepackage{color}
\usepackage{apacite}
\usepackage[english]{babel}
\usepackage{csquotes}
\MakeOuterQuote{"}
\counterwithout*{footnote}{chapter}
The only mention of leftmargin in the .cls is here:
% VERSE
% The verse environment is defined by making clever use of the
% list environment's parameters. The user types \\ to end a line.
% This is implemented by \let'in \\ equal \@centercr.
%
\def\verse{\let\\=\@centercr
\list{}{\itemsep\z@ \itemindent -1.5em\listparindent \itemindent
\rightmargin\leftmargin\advance\leftmargin 1.5em}\item[]}
\let\endverse\endlist
% QUOTATION
% Fills lines
% Indents paragraph
%
\def\quotation{\list{}{\listparindent 1.5em
\itemindent\listparindent
\rightmargin\leftmargin\parsep 0pt plus 1pt}\item[]}
\let\endquotation=\endlist
% QUOTE -- same as quotation except no paragraph indentation,
%
\def\quote{\list{}{\rightmargin\leftmargin}\item[]}
\let\endquote=\endlist
% DESCRIPTION
%
% To change the formatting of the label, you must redefine
% \descriptionlabel.
\def\descriptionlabel#1{\hspace\labelsep \bfseries #1}
\def\description{\list{}{\labelwidth\z@ \itemindent-\leftmargin
\let\makelabel\descriptionlabel}}
\let\enddescription\endlist
\newdimen\descriptionmargin
\descriptionmargin=3em

I do not have any BCOR. Is there somewhere else binding correction would occur?
I've reviewed these questions, but to no avail. Why is my left margin slightly larger than my right margin Left margin wider than right one
Edit; even after adding:
\usepackage[pass,letterpaper]{geometry}
The result is still unchanged


uclathes... Do you use doublesided printing with binding correction? Then the inner margin is binding correction + inner margin. – Mensch Mar 16 '19 at 21:37
