HOW IT WORKS

LESSONS

For learners needing extra Physical Science classes, but who cannot afford or access them locally, YouCanDoScience provides the opportunity to master Physical Science at their own pace, in the comfort of their home, whenever it suits them. The manner in which the lessons are compiled make it ideal for homeschooling.

For learners needing to rewrite the supplementary Physical Science exam, the revision lessons, providing a comprehensive summary of each component, are just what they need. They will also have access to detailed concept lessons if they need to go back to the basics, and a comprehensive science dictionary.

The lessons are structured in such a way that makes them an ideal aid for holiday science camps or autumn-, winter-, or spring holiday schools, where learners can revise concepts or catch up with missed Physical Science lessons. Furthermore, they offer guidance to less experienced teachers on how to present difficult concepts.

Companies with CSI responsibilities can sponsor learners or schools, at a very affordable rate, in the areas where their workers are drawn from. The Report Back function allows the CSI manager to follow the progress of sponsored learners.
