+\section{Introduction}
+\begin{itemize}
+	\item Introduction to the problem: the absence of proper examination
+	      software with support for specific learning areas.
+	\item Paper composition
+\end{itemize}
+
+An examination is an assessment intended to measure a test-taker's knowledge
+and skills in a topic. An exam may be administered orally, on paper or on a 
+computer. However, even in the current computer based age, most of the exams
+are still administered on paper. This raises the first question: What is the 
+reason of the lack of computer based exams? 
+can all topics administered on a computer? 
+
+
+\section{The problem}
+\begin{itemize}
+	\item Extended definition of the problem with some concrete examples
+\end{itemize}
+
+\section{Conceptual solution}
+\begin{itemize}
+	\item Demands that the solution should meet
+\end{itemize}
+
+\section{Existing E-Learning software}
+\begin{itemize}
+	\item Explain how existing ELO's and examination applications are short
+	      of the above demands
+\end{itemize}
+
+\section{Realized solution}
+\begin{itemize}
+	\item Our solution to the problem (web application), how does this
+	      meet the specified demands?
+	\item How we add value above the existing ELO's
+\end{itemize}
+
+\section{Conclusions and future work}
+\begin{itemize}
+	\item Conclusion: our solution is not just another ELO, it's a new concept
+	      that completes the digital learning experience.
