When writing my thesis i faced a problem, how to avoid displaying Appendix section from TOC, i found a coding solution in StackOverflow.com and i modified it to allow up to 3 levels.
Just add these Command after the preamble of your document and use them as following:

\newcommand{\hiddensection}[1]{
\stepcounter{section}
\subsection*{\arabic{section}\hspace{1em}{#1}}}

\newcommand{\hiddensubsection}[1]{
\stepcounter{subsection}
\subsection*{\arabic{section}.\arabic{subsection}\hspace{1em}{#1}}} 

\newcommand{\hiddensubsubsection}[1]{
\stepcounter{subsubsection}
\subsection*{\arabic{section}.\arabic{subsection}.\arabic{subsection} \hspace{1em}{#1}}}

Now you can use the new commands as following:

\hiddensubsection{SubSectionName}
instead of \subsection{SubSectionName}

\hiddensubsubsection{SubSubSectionName}
instead of \subsubsection{SubSubSectionName} 

To allow good Appendix table of content view and writing professional documents, follow this piece of code:

Note that , appendix1 and appendix2 is a normal .tex files like any chapter files start with \chapter and contains sections

\usepackage[titletoc]{appendix}
