If you are on this MOOC, it is that IT and digital are not completely foreign to you.
This level will therefore be devoted to a reminder of some basic manipulations and a few points of attention to move around in an online tool using the example of this MOOC.
In this level, there is no video of course because it is rather to review and then validate things that you have already done.
Do the training exercises and if you did not get the maximum points in these exercises, understand your mistakes by carefully reading the correction that is given to improve your score in the validation test.
