The price is not just the total price, but a comprehensive comparison based on the number of class hours, class size and class frequency. If you only refer to the total price of the course without comparing the class hours and class numbers, for example, the price is the same, the class number is the same, but the class number is different, VIP 1 right 1, 1 right 2, the oral practice services and opportunities enjoyed by small classes and large classes are different, so you must carefully measure them.
