How can I get the \rhead superiorly to the top and \chead down?

Question

MWE

\documentclass[12pt,a4paper]{article}


\usepackage{enumitem}
\usepackage{fancyhdr}
\usepackage[margin=3cm]{geometry}
\usepackage{pgfplots}



\newlength{\tabcont}
\setlength{\parindent}{0.0in}
\setlength{\parskip}{0.05in}


\title{Assignment 4}


\newcommand{\course}{lipsum}
\newcommand{\coursen}{lipsum}
\newcommand{\semester}{lipsum}
\newcommand{\TDAG}{lipsum}
\newcommand{\campus}{lipsum}
\newcommand{\dept}{lipsum}



\pagestyle{fancyplain}
\headheight 56.2pt

\chead{\campus \\ \dept \\ \course \\ \coursen }
\lhead{\TDAG}
\rfoot{\thepage}
\begin{document}

The solution I want

After compiling the above document, the \rhead and \chead are similar in position of height. I want the \rhead to be up and \chead to be down/after \rhead.

I have reviewed a post that included something like \header[C], but that did not work. I am using Miktex + texMaker. But do provide an example if you know how to do it with \header[C] :)

You could just wrap the central header in a minipage:

\documentclass[12pt,a4paper]{article} 


\usepackage{enumitem}
\usepackage{fancyhdr}
\usepackage[margin=3cm]{geometry}
\usepackage{pgfplots}



\newlength{\tabcont}
\setlength{\parindent}{0.0in}
\setlength{\parskip}{0.05in}

\pagestyle{fancyplain}
\headheight 56.2pt

\chead{\begin{minipage}[t]{.3\textwidth}
