For example, some students are excellent, their GPA is very high at school, the admission conditions of the colleges they apply for are very clear, their language scores can reach the standard, and they can even get letters of recommendation and translations, various notaries and deposit certificates. Then I don't think it is necessary to find an intermediary to spend more money, but I can also improve my ability and exercise.
If you don't know much about the details of studying abroad, the requirements and conditions of the other country and institution, or your DIY visa has been refused, and your GPA score is not enough, then you need intermediary assistance to study abroad, with high success rate and no worries.
So choose the topic according to your own situation. If you choose an intermediary, you should also keep your eyes open and choose a professional institution. Some small organizations may have only two or three people and a small studio. It is very likely that you will be empty soon after you pay the money. How to choose an intermediary, please trust me privately, otherwise someone will think I am an advertisement.
