Different people learn in different ways...
● Some are visual learners and grasp concepts fast using pictures and images
● Some are aural learners with an ear to listen better than others
● Verbal learners will read out loud to remember.
● Some are physical learners they use their hands, fingers, etc. to remember what they study.
● Logical learners remember concepts through logical reasoning. They create flowcharts or analyze them and use them as a method of learning.
You can choose the method which you feel can help you learn faster. Also, check if you learn better when alone or when you are in a group study.
