For takes notes I have attention in class and I make the teacher's explications in the notebook.
When I don't understand anything from the lesson, I ask the question to the teacher because maybe is necessary to clear doubts.
When the teacher is writing in the whiteboard and I take in the notebook the teacher's explication.
I write different words when I pass to another subject, for exemple in maths I take equations in the notebook and how is it done. In catalan I write in the notebook the words and the important explications and I underline in different colors the more important words because it's the better way to remember these words.
Thanks for your attention !!!!
