You have 30 minutes total for 12 questions, which averages about 2.5 minutes per question—but that's tight. Most test-takers find Multi-Source Reasoning and Table Analysis questions consume more time since they require reading multiple sources or analyzing complex data sets. A strategic approach is to start with question types you're strongest in, build confidence and time cushion, then tackle harder formats. Tutors help you develop pacing strategies specific to your strengths and weaknesses rather than aiming for uniform timing across all question types.

The biggest mistakes are: (1) spending too long analyzing data before reading the question, (2) misinterpreting what the graphics actually show—percentages vs. absolute numbers, for example, (3) missing hidden assumptions in Two-Part Analysis questions, and (4) not reading answer choices carefully before submitting. Many students also underestimate how much reading is involved; IR has roughly 30% more text than the Verbal section, so strong reading comprehension directly impacts IR performance. Identifying which mistakes are holding you back—through practice tests and error analysis—is where personalized instruction makes the biggest difference.

Score improvement on IR varies more than other GMAT sections because many test-takers have limited exposure to these question types before studying. With focused practice and strategic tutoring, students typically see 3-5 point improvements (on the 1-8 scale) over 4-8 weeks, though larger gains are possible if you're starting from a lower baseline. The key is practicing under timed conditions with real GMAT questions, analyzing errors systematically, and addressing the specific question type that's holding you back. Personalized tutoring accelerates improvement because tutors identify whether your struggles stem from time management, conceptual gaps, or test anxiety—then target that root cause.

Effective IR practice has three phases: (1) learn each question type in isolation with untimed practice to build familiarity, (2) move to timed practice within the section, and (3) take full practice tests to experience the fatigue and pacing pressure of all four GMAT sections together. Many students skip phase one and jump straight to timed practice, which creates frustration and inflates error rates. Quality matters more than quantity—analyzing why you missed 5 questions tells you far more than rushing through 50. Tutors help you structure practice sessions strategically, identify patterns in your mistakes, and adjust your approach based on what the data reveals about your performance.

For students in Los Angeles preparing for the GMAT, personalized tutoring addresses IR challenges that group classes often miss. Tutors work with you to diagnose whether your problem is conceptual (not understanding how to interpret graphs), strategic (poor time allocation), or psychological (rushing through questions due to anxiety). They provide customized drills targeting your weakest question types, teach you to recognize question patterns quickly, and help you develop a personal pacing strategy based on your actual strengths. Since IR is unique compared to other standardized tests, many students benefit from expert guidance that breaks down each question type's underlying logic.

The short answer: less, but not insignificant. Business schools primarily focus on your Quantitative and Verbal scores, which together create your composite GMAT score (200-800). IR is scored separately on a 1-8 scale and is considered an additional data point showing analytical thinking—but a strong Quant/Verbal score with a weaker IR won't disqualify you from top programs. That said, if you're aiming for a competitive school, demonstrating competence across all sections signals well-rounded analytical ability. Rather than viewing IR as optional, think of it as an opportunity to show you can tackle complex, multi-step problems under pressure—exactly what MBA coursework requires.
