I am math teacher in secondary school and I have a few thousands of mathematical exercises in many Microsoft Word files.
I tried to organize them in folders and keep track of new exercises to update my content, but it was hard working with many different type of exercices. I was thinking to create a web app for personal use where I could add all the exercises and also implement a query system to retrieve only those I want to create exams papers with specific difficulty or specific chapter. But, I had a problem with exercises with tables, bullets and not just simple text and math symbols.
I am looking for a software which help you to organize and categorize all your exercises and make your life as a teacher easier.
Edit: I am looking a software to organize the exercises and not the documents. For example, in the web app I tried to create, I had to import the exercises one by one including meta-tags like difficulty, tags, chapters, images etc. With that way, I could run a query to retrieve all the exercises with specific tag or difficulty.
