IBDPmaths - Asynchronous E-learning Platform  

Math Studies SL e-Learning Course


This new e-learning course completely covers the IB Diploma Programme in Mathematical Studies SL and will help students achieve the highest grade possible for their examination. It supplements textbooks and teaching notes. Sound combinations of visual and audio aid allow the students either while in class or on their own to be exposed on a different type of learning. The use of such a digital set of aids shows once more that technological applications as such can on a rather straightforward but well focused manner aid learners to master mathematics on a young age as possible in the most effective and less stressful way.
