Offline courses are inconvenient. Second, most offline courses need unified time, which is inconvenient for some working parties or student parties. Third, there are a large number of offline classes, and teachers with limited energy may not be able to answer all students' questions. So I think it's better to report offline courses one by one.

However, this will also face a problem, that is, the tuition fee is too high. From this perspective, it is also one-on-one, and online classes seem to be more cost-effective.

Then the problem is coming. Even for online courses, there are gaps between institutions. Choosing which one is better has become a concern of everyone.

Personally, I think what suits me is the best.

Now there are free audition courses in GMAT institutions. Students who want to choose between institutions may wish to listen to their audition courses and see if the teacher's method, logic and lecture style are suitable for them.

If you still don't know how to choose after listening to the course, here are some suggestions:

1. Teacher

When a teacher attends class, the higher the strength of the teacher, the better. Here you can see the brief introduction of their teachers, some past teaching cases, and the courses that official website is responsible for in various institutions.

2. Your own situation

Everyone has their own weak points in learning, and they also need to focus on making up lessons. Many institutions have specialized knowledge upgrading courses. It is suggested that you know your basic situation before applying for the exam, such as what my target score is, whether I have exam experience, where my weaknesses are, and then apply for classes in a targeted manner.
