You can simply add bullet points in you LaTex tables, there is a sample which I hope it helps:
\documentclass{article}
\begin{document}
\begin{tabular}{|p{0.4\textwidth}|p{.03\textwidth}|p{0.4\textwidth}|}
%%%
\begin{itemize}
\item Sample Text
\item Sample Text
\end{itemize}
& Hi &
\begin{itemize}
\item Sample Text
\item Sample Text
\end{itemize}\\
%%%
\begin{itemize}
\item Sample Text
\item Sample Text
\end{itemize}
& Hi &
\begin{itemize}
\item Sample Text
\item Sample Text
\end{itemize}
%%%
\end{tabular}
\end{document}
The output would be like:
Also in your code, you need to drop the l and work with p:
\documentclass{article}
\begin{document}
\noindent \begin{tabular}{|p{0.6\textwidth}|p{0.6\textwidth}|}
\Large{Education} & \textbf{University} \\
& Degree, Major, May 2018. \\
\begin{itemize}
\item Course 1
\item Course 2
\item blah, blah.
\end{itemize}
\end{tabular}
\end{document}

itemizecan't be used inside anl- columntype (at least not this way!). Replace the firstlwithp{2in}, i.e. making a parbox - column of width2in. You can choose another width of course – Sep 11 '16 at 05:51cvormoderncv-class? – naphaneal Sep 11 '16 at 07:50
