I give private classes for children in ESO, especially in mathematics, chemistry, and English. The study plan is to advance with the proposed syllabus in your own institute, and do the activities both from the book and extra, if necessary. Things will be explained as many times as necessary, but at the same time a little responsibility will be asked from the student. If he gets involved, he will be able to understand your doubts. I like to make summaries or diagrams with key ideas, send exercises for them to practice, and all this in a comfortable environment, without overwhelming the student.
