Is toolkit mandatory?

The Toolkit is an optional extra, a sunroof if you will.
Very nice to have, very helpful, but if needed you can live without. I would recommend both our Toolkit and a sunroof but that is your choice.

It is not mandatory. 

The Toolkit includes
Webinar Slides for every class
Summary Notes for every class
Bonus Videos

It has proven to be popular as supporting materials for the classes and revision notes.
Students using Toolkit very often have both higher completion rates and grades for their courses.

It can also be downloaded and saved on your device for future references, even after your access period expired.
