[Tex/LaTex] horizontally centered text in minipage

minipage

I have a problem with the horizontal align of the text within a minipage environment.

Below is my code.

\documentclass[12pt,paper=a4,answers, addpoints]{exam}
\usepackage{graphicx,lastpage}
\usepackage{upgreek}
\usepackage{censor}
\usepackage{amsmath}
\usepackage{eurosym}
\censorruledepth=-.2ex
\censorruleheight=.1ex
\hyphenpenalty 10000
\usepackage[paperheight=10.5in,paperwidth=8.27in,bindingoffset=0in,left=0.8in,right=1in,
top=1in,bottom=1in,headsep=1.5\baselineskip]{geometry}
\flushbottom
\usepackage[normalem]{ulem}
\usepackage[utf8]{inputenc}
\renewcommand\ULthickness{2pt} %%---> For changing thickness of underline
\setlength\ULdepth{1.5ex}%\maxdimen ---> For changing depth of underline
\renewcommand{\baselinestretch}{1}
\pagestyle{empty}

\pagestyle{headandfoot}
\headrule
\newcommand{\continuedmessage}{%
\ifcontinuation{\footnotesize Question \ContinuedQuestion\ continues\ldots}{}%
}
\runningheader{\footnotesize Dipartimento di Economia}
{\footnotesize Analisi delle Politiche Pubbliche -- LM56}
{\footnotesize Pagina \thepage\ di \numpages}
\footrule
\footer{\footnotesize}
{}
{\ifincomplete{\footnotesize Question \IncompleteQuestion\ Continua nella pagina successiva}{\iflastpage{\footnotesize \textit{\bfseries Fine domande di esame}}{\footnotesize \textit{\bfseries Continua nella pagina successiva}}}}

\usepackage{cleveref}
\crefname{figure}{figure}{figures}
\crefname{question}{question}{questions}
\renewcommand\thequestion{\arabic{question}}
\renewcommand{\questionlabel}{\thequestion)}
\renewcommand{\questionshook}{%
\setlength{\leftmargin}{0pt}%
\setlength{\labelwidth}{-\labelsep}%
}

\nopointsinmargin 
\pointpoints{Mark}{Marks}

\marginpointname{\points}
\pointformat{\boldmath\themarginpoints}
\bracketedpoints

\begin{document}

\thispagestyle{empty}

\noindent
\begin{minipage}{.20\textwidth}
\includegraphics[width=2.5cm]{logo} 
\end{minipage}
\begin{minipage}[c]{.65\textwidth}

\end{document}

My problem is that I would like to have the text in the red box horizontally centered. Is there any chance I can get this? Thanks in advance

ADDENDUM

After suggestion made by David, this is what I got. I am not sure whether the text seems to be closer to the logo on the rhs because of an optical effect or it is in fact closer. The picture of the result is below:

SECOND ADDENDUM

After suggestions by David, I modified my code as follows:

\documentclass[12pt,paper=a4,answers, addpoints]{exam}
\usepackage{graphicx,lastpage}
\usepackage{upgreek}
\usepackage{censor}
\usepackage{amsmath}
\usepackage{eurosym}
\censorruledepth=-.2ex
\censorruleheight=.1ex
\hyphenpenalty 10000
\usepackage[paperheight=10.5in,paperwidth=8.27in,bindingoffset=0in,left=0.8in,right=1in,
top=1in,bottom=1in,headsep=1.5\baselineskip]{geometry}
\flushbottom
\usepackage[normalem]{ulem}
\usepackage[utf8]{inputenc}
\renewcommand\ULthickness{2pt} %%---> For changing thickness of underline
\setlength\ULdepth{1.5ex}%\maxdimen ---> For changing depth of underline
\renewcommand{\baselinestretch}{1}
\pagestyle{empty}

\pagestyle{headandfoot}
\headrule
\newcommand{\continuedmessage}{%
\ifcontinuation{\footnotesize Question \ContinuedQuestion\ continues\ldots}{}%
}
\runningheader{\footnotesize Dipartimento di Economia}
{\footnotesize Analisi delle Politiche Pubbliche -- LM56}
{\footnotesize Pagina \thepage\ di \numpages}
\footrule
\footer{\footnotesize}
{}
{\ifincomplete{\footnotesize Question \IncompleteQuestion\ Continua nella pagina successiva}{\iflastpage{\footnotesize \textit{\bfseries Fine domande di esame}}{\footnotesize \textit{\bfseries Continua nella pagina successiva}}}}

\usepackage{cleveref}
\crefname{figure}{figure}{figures}
\crefname{question}{question}{questions}
\renewcommand\thequestion{\arabic{question}}
\renewcommand{\questionlabel}{\thequestion)}
\renewcommand{\questionshook}{%
\setlength{\leftmargin}{0pt}%
\setlength{\labelwidth}{-\labelsep}%
}

\nopointsinmargin 
\pointpoints{Mark}{Marks}

\marginpointname{\points}
\pointformat{\boldmath\themarginpoints}
\bracketedpoints

\begin{document}

\thispagestyle{empty}

\noindent
\begin{minipage}{.17\textwidth}
\begin{flushleft}
\includegraphics[width=2.5cm]{logo}
\end{flushleft} 
\end{minipage}
\begin{minipage}[c]{.66\textwidth}\centering
{\bfseries Ph.D. in Economics, Management and Statistics}\par
\medskip
{\bfseries University of Catania \& University of Messina}\par
\medskip
\end{minipage}
\medskip
\begin{minipage}{.17\textwidth}
\begin{flushright}
\includegraphics[width=2.5cm]{logo-unict}
\end{flushright} 
\end{minipage}
\par
\vspace{-3ex}
\begin{center}
\textit{\bfseries \LARGE{Microeconomics}}\par
\end{center}
\vspace{-3ex}
\begin{minipage}{\textwidth}
{\bfseries Lecturers:}
\begin{tabular}[t]{@{}l@{}}
  Dr. X\\
  Dr. Y\\
  Dr. Z\\
\bigskip
\end{tabular}
\end{minipage}
\begin{minipage}{\textwidth}
\textit{\textbf{Name:}}{\hrulefill}\par
\bigskip
\textit{\textbf{Signature:}} {\hrulefill}\par
\bigskip 
\end{minipage}
\begin{center}
\rule{\textwidth}{1pt}
\end{center}
\end{document}

It works fine now. The result is below:

You don't have to guess dimensions, leave the computations to TeX.

\documentclass{article}
\usepackage[
  paperheight=10.5in,
  paperwidth=8.27in,
  bindingoffset=0in,
  left=0.8in,
  right=1in,
  top=1in,
  bottom=1in,
  headsep=1.5\baselineskip,
  showframe,% just for the example

\usepackage{graphicx,varwidth}
