What is the best way to concentrate and study?

One way is to have a positive attitude. When you have a positive attitude, you're more likely to do better too. Another way is to study in a quiet place with no distractions.

The best way to concentrate and study is by using these three thing 
First, your eyes they must sharp and ready to read and to focus on what is more important games or education.
Next, ears they should ALWAYS be alert ready to hear what the teacher has to say ready to hear everything you have to know.
Last, Brainstorm when you brainstorm think very hard on whatever you have to do like for example science.
