This is a particularly important point. There are several types of learning, but the most common are theoretical and logical. The former is a lot about memorization and knowing facts, so if you are this type of learner, subjects like history or social studies probably suit you quite well. The logical type of learner is all about deduction and getting to the essence, such as a mathematical equation, so STEM subjects (math, computer science, science, technology) suit this type of learner best.
