Is it necessary to take a GMAT prep course, or can self-study be sufficient?

A prep course can be helpful, but it’s not a must for everyone. Some test-takers do really well with self-study, especially if they’re disciplined and know where their weak areas are. It mostly depends on how comfortable you are with the format and whether you’re able to stay consistent on your own.

Courses are useful if you’re short on time or need structure. They also help if you want guided practice and fast feedback. But with the right materials and a solid routine, many people manage to score well through self-study alone.

So it’s less about what’s necessary and more about what suits your study style. Both paths work — what matters is how committed you are to the plan you choose.
