Should we use all existing resources (quizzes, mini-projects, final projects)?
It’s up to mentors whether to use existing resources or to make a completely new one. And even if mentors decide to use existing resources, you are free to choose which and how many resources you want to use. You are not required to use all of the existing resources.
For example, if there are 4 existing mini-projects for Day 1 of Computer Science 101, that just means you have 4 choices of mini-projects to choose from, not that you have to do all 4 activities in one day.
