Private classes

I think that private class is a good way for students to improve their knowledge and have a great advancement if you compare it with a regular course. However it’s more expensive and the student needs to spend more money.
The advantage is that the teacher gives attention all the time for you, so you have conditions to develop very quickly from their knowledge.
Only you answer questions made by the teacher, you talk more because you don’t need to divide the class time with other students. Furthermore you need to study hard and dedicate more.
Teachers are evaluating the student all the class and have conditions to change the class in real time to attack a negative point shown for by the student.
