Free Schematics And Circuit Diagrams Pioneer What Products / Software Should I Get For Taking Notes In A Classroom?

What products / software should I get for taking notes in a classroom? - free schematics and circuit diagrams pioneer

I am 2nd Technical years studying computer science and my handwriting sucks, but I type 90 words per minute!
Then I realized that writing can be a lot easier.

But the fact remains that I have a lot of graphics and tables in a conference (circuits, diagrams, ...)
I thought of a pill to bring my laptop.

What type and size should I expect? Is there software (preferably free) that it is much easier to integrate all the notes and symbols and diagrams, easy to get?


Thank you!
