Write down the headings, leaving space in between for main points, then write main points, leave space for sub points, etc. As for lectures, try to only write down the main points, and then later rewrite your notes as an outline because it's probably an incomprehensible mess.
Afterwards, write good questions based off the main points on a new page or 1 question per index card. Write simple ones. Don't do "what are the characteristics of the atlantic ocean?", subdivide it into several simpler questions "the atlantic ocean is x meters wide," "the atlantic ocean is know for x." etc.
Now you just need to review the questions to study. Answering questions is better than rereading shit, which doesn't actually reinforce your learning.
Also, for math or other subjects with problem solving, try to find some problem sets and answer them. It's worthless to just memorize conceptual stuff without applying it.
Now just spread out your review after your first review. It's inefficent to study the same material over and over again next day, unless you have an exam.
