* Your current skill level: If you have some basic math skills but lack confidence or haven't used them in a while, it will take longer than if you have a stronger foundation. Someone who hasn't seen algebra or geometry in years will need more time than someone who recently completed college-level math courses.
* Your study habits: Consistent, focused study for shorter periods is far more effective than cramming. A dedicated study plan and disciplined approach are crucial.
* Your target score: A higher target score naturally requires more preparation time. A score of 600 might be achievable with less study than a score of 700 or higher.
* Your learning style: Some people learn quickly and retain information easily, while others need more time and repetition.
* Your available study time: Can you dedicate several hours a day, or only a few hours a week? This dramatically impacts your timeline.
Considering these factors, a reasonable estimate for a non-math student aiming for a respectable score (e.g., 600-650) is 3-6 months of dedicated study. This assumes a consistent study schedule of several hours per week. If you have a weaker math background, you might need closer to 6 months, or even longer. For higher scores (700+), expect a longer preparation time, possibly 6-9 months or more.
Crucially, focus on building a strong foundation in math. This might involve starting with basic algebra and geometry review before tackling GMAT-specific material. Consider using resources like Khan Academy to build this foundation.
Don't just focus on the length of time; focus on consistent progress and effective study strategies. Using practice tests regularly, identifying weaknesses, and focusing your study efforts on those weaknesses are key components of successful GMAT preparation.
