The course structure

Every activity contains some steps where Alberto or Carlo explain the main topics. This will be followed by one or two Let’s count steps, where you’ll find some exercises and a video where we show you their way to solve some of them.

It is very important that you try as much as you can to solve the exercises, or discuss the solutions with the other learners, before you watch the video. In any case, you’ll find a PDF file with the solutions to all the exercises at the bottom of each step.

Steps are self-contained, but it is necessary to study the main topics in the order proposed here before going further.

In the video solutions, if you have any trouble reading the handwriting on the board, don’t worry – you can always follow along in the transcript and in the attached PDF.

At the end of almost every activity you’ll find a Quiz step with 3 quizzes each , where you can check and practise what you jave learned. Please do not hesitate to review the content of the activity if you solve at most 1 quiz over 3.
