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).}
