google coursebuilder - what is the best way to add assessment or quiz?

[itcn2cse]

Hi,

We are using the course-builder platform for our course. In the current template there are only 3 assessment available: Pre, Mid, and Fin.
What would be the best way to add more assessment? What parameters should be added in the code and in which files.

Another question: what is the best way to limit the number of attempts for each assessment and how to store the grades for every attempt.

Thanks,
Michael.
