This fee will vary in different schools, especially between well-known business schools and ordinary local universities. The former often charges more because of the advantages of brand, teachers and resources, while the latter is relatively economical.
Fees also vary according to the type of registered classes. Some institutions offer online courses, some offline courses, and some combine online and offline courses. Generally speaking, the cost of offline courses will be higher, because it involves more physical resources and human input.
Some institutions may offer some preferential and promotional activities, such as providing discounts at a specific time or for a specific student group.
To sum up, the cost of MBA professional training is a relatively broad range, and the specific cost needs to be selected according to personal needs and goals. If you are interested in a particular school or institution, I suggest you contact them directly for more detailed information.
