Consulting and intermediary are obviously different. Consultation only tells what materials need to be prepared, how to obtain these materials, how to fill them out, how to pass them easily, etc. Intermediaries are institutions that assist in handling relevant institutions. In reality, if it is a consulting company, we must look at its business qualifications, not just listen to its words.
Intermediaries usually cooperate with foreign institutions to recruit students as agents. School won't be very good. Take Top 10 in America as an example, it is impossible to cooperate with them. There is definitely no chance for you to go to them. There may even be diploma workshops. If there is no proxy enrollment, you will consider students' wishes and soft and hard conditions when choosing a school, choose the most suitable school, and the teachers are relatively more professional.
