Your visual intelligence can benefit from different colours, shapes or positions when you study or take notes.
Using a colour code can help you understand the different diagrams. If you always choose a certain colour for a topic and a different one for the subtopics, you’ll easily get it.
Another way of doing the same is by using different shapes, likes dots, arrows or whatever you like.
Making proper diagrams will make your notes look tidy and it’ll be useful. If you combine them with the above, studying your own notes will be a pleasure as the information will be stated just like you prefer best.
But always remember to take your own notes and personalize them at your preference.
