Best way to change font size (prometheusCV on Overleaf)

I want to change the overall font size in section headings and sub-headings, but I'm having a hard time doing so.

For example:

    \textbf{M.Sc.}~in Trickery\begin{large}
        ~(summa cum laude)
    \end{large}}

I did this to change font to one of the sub-headings, but still having trouble chaning the font size in the main headings like Education.

Do you have any suggestions to make it more readable. When I export to pdf, it everything looks so small. Thank you.

prometheu-cv use the titlesec package to customize section and subsection titles.

You can define your own style by issuing before \begin{document}

% Customise the \section command 
\titleformat{\section}         
{\Huge \scshape\raggedright} % Make the \section headers Huge, small caps and left aligned
{}{0em}                      % No label (prefix) and no horizontal separation between label and title body
{}                           % Code preceeding the title body
[\titlerule]                 % Code following the title body. Here a horizontal line.

%  \subsection command
\titleformat{\subsection}
{\Large\scshape\raggedright}
{}{0em}
{}

To change the font size of just a few words, it is better to type {\Large (summa cum laude).}
