Hi @ktabucal,
Did all of you get the same assignment for your classes? 😆
In my opinion, the best learning materials are interactive lessons. Please continue watching them. They will show you all the most important tools available in Alteryx.

The second thing would be having a goal to achieve certification:

Here you have all information about the requirements for Core certifications:

A great resource of knowledge is also weekly challenges. After you will complete all the interactive lessons please go to the weekly challenge index and check the data preparation challenges for the beginner level.
If you will be interested in one particular topic you can also check the video lessons. They are available below:
