Can I self-study for the GRE or do I need a course/tutor?

Many students successfully self-study for the GRE using official ETS materials and a structured study plan. A course or tutor becomes valuable when you've plateaued and can't figure out why, when you need accountability, or when you're targeting a very high score and need expert guidance on strategy. Start with self-study and consider getting help if you stop seeing improvement.
