السلام عليكم ورحمة الله أحسن الله إليكم I need some advice on how to take notes properly: should I buy the book we're studying and write notes on it, or buy a separate notebook for each course, or one notebook with all notes from all lessons mixed together? And where can I buy the books in Arabic?

Your notes should be on the book you are studying. This is the most effective wat in my eyes.
