In class or in lectures, you should always keep your ears open. That way you can absorb new content quickly. If you talk or daydream with the person sitting next to you, you miss important material. This has to be painstakingly revised later at home. What is also helpful is taking notes. A study shows that students who take notes remember more important information than fellow students who just listen. The decisive factor here is the type of minutes. Those who just take notes quickly lose the overview. The study shows the greatest learning success with economic notes that only record the essentials. The effect is even greater if the new knowledge is linked to existing knowledge. This prior knowledge makes it easier to reduce the material to the essentials. This in turn makes learning easier. The more care and attention this takes, the greater the learning success.
