This website was built to help students cope with their daily problems in mathematics.
The main goal is to help them discover their gaps in knowledge. Inevitably the website is based on Backward Curriculum Design (Mapping).
Each lesson at the beginning has a section called "What you have to know". Students first must check if they are familiar with these concepts mentioned before studying the current lesson. If not, they can follow the links to discover any missing "holes" in their knowledge.
The website is being updated constantly.
