Hi
ParthVatsWhile looking for a course there's the obvious factors that one looks for - cost, content and teachers. But I'd recommend that you look for some other factors as well.
1. Look for a course that not only teaches you concepts but also teaches you the application of these concepts. GMAT is a test of application skills and as such this is a crucial factor. A course that teaches you a structured way of solving questions is very important if you want to score 645+ on GMAT Focus.
2. It should provide you with a clear and structured study plan. Your focus should be only on learning and not struggling with what and how to study. Look for a course that provides you with the guidance for the same.
3. It should give you detailed feedback on your performance and show you exactly where you can improve
4. It should offer doubt solving support along with dedicated mentors who guide you throughout your GMAT journey.
The best way to find out the right online course for your preparation is to check out the free trial and see if their pedagogy suits you. Do check out the above factors before enrolling to a course.
