What is the GMAT and who needs it

The GMAT (Graduate Management Admission Test) is the most widely used test in the world for admission to MBA, Executive MBA and management master's programmes. It is administered by GMAC (Graduate Management Admission Council) and accepted by over 7,700 programmes at more than 2,400 institutions.

If you want to get into SDA Bocconi, INSEAD, London Business School, HEC Paris, IE Business School — or any American MBA — the GMAT is almost always required or strongly recommended. For those targeting Bocconi, we have a dedicated guide to Bocconi test preparation that also covers the MBA path. Even when a programme accepts the GRE as an alternative, the GMAT remains the clearest signal that you are aiming for the business world.

The current format was introduced by GMAC in 2024, still sometimes called the "Focus Edition" even though it is now simply the GMAT. All official information can be found on the official GMAT Focus Edition page on mba.com. Compared to the previous version, it is shorter, more focused and includes some important changes we will cover shortly.

For a detailed look at what changed from the old GMAT: GMAT Structure: Sections, Scoring and How It Works

Structure: the three sections in brief

The GMAT has 64 questions divided into 3 sections of 45 minutes each, for a total of 2 hours and 15 minutes — significantly shorter than the 3 hours and 30 minutes of the previous version (plus an optional 10-minute break).

Three features that change how you prepare:

You choose the section order. Before starting the test, you decide which section to begin with. This is not a detail — it is a strategic lever. If Quant is your strength, you can start there to build confidence. If you know Verbal tires you out, don't put it last.

You can review and change answers. Up to 3 answers per section, if you have time left. This changes the strategy: you can flag questions you're unsure about and come back to them.

The test is adaptive at the section level, not by individual question. The difficulty of questions in the second half of each section adapts to your performance in the first half. You will not see your score during the test — but you will feel the difference in difficulty.

Scoring: how it works and how much you need

The total score ranges from 205 to 805, in increments of 10 points. Each section is scored separately on a scale from 60 to 90, in increments of 1 point. All three sections carry equal weight in the total.

Here is how to read the numbers in practical terms:

An important note: the new GMAT score is not directly comparable to the old one. A 645 on the current format is roughly equivalent to a 700 on the old 200-800 scale. Business schools have adapted, but when you read "average GMAT 710" on a site that does not specify, it may refer to the old scale.

The score is valid for 5 years and with ScoreSelect you can choose which attempt to send to schools.

How long to prepare

GMAT preparation takes 8-16 weeks depending on your starting point: 8-10 weeks for those with a solid quantitative background (STEM degree, working with numbers daily), 12-16 weeks for those from a humanities background. The average commitment is 15-20 hours per week, with consistency mattering more than study marathons.

If you start with a strong quantitative background (STEM degree, work with numbers every day): 8-10 weeks of structured preparation, 15-20 hours per week. Realistic target: 615-665.

If you start from scratch or nearly so (humanities background, years without doing math): 12-16 weeks, with the first 4 dedicated to rebuilding the foundations. Realistic target: 100-150 point improvement from the diagnostic.

If you are aiming for 695+ (top programmes): add 4-6 weeks of refinement after reaching 615-645. The marginal points above 650 are the most expensive in terms of time.

The most underestimated variable is consistency. One hour a day for 3 months beats 5 hours on the weekend for 6 weeks. The GMAT tests pattern recognition and decision-making under pressure — skills that are built through distributed repetition, not marathons.

Detailed plan for every scenario: When to Take the GMAT: Timing and Planning

Section-by-section strategies

Each GMAT section requires specific strategies: Quant rewards backsolving and aggressive time management (2:08 per question), Verbal requires reading for structure rather than details (1:57 per question), and Data Insights combines five different formats with the calculator available. Here are the techniques that work for each.

Quantitative Reasoning: 21 questions, 45 minutes

The current GMAT Quant section is problem solving only — no Data Sufficiency (moved to Data Insights) and no pure geometry. What remains: arithmetic, algebra, equations, inequalities, percentages, ratios, probability, combinatorics.

The good news: if you attended a scientific high school or earned a STEM degree, you already know 90% of the theory. If you have gaps, math tutoring with a dedicated tutor can fill them in a few weeks. The bad news: knowing it is not enough. The GMAT does not test whether you know a formula — it tests whether you apply it quickly under pressure, recognising which approach to use within 30 seconds.

Average time per question: ~2 minutes and 8 seconds. You cannot use a calculator.

Three things that work:

Learn to recognise traps. The GMAT presents questions so that the most intuitive solution is often wrong. "Too clean" answers (round numbers, obvious results) are often decoys. Train yourself to ask "why does this seem easy?" before answering.

Work backward from the answers. In many questions, substituting the answers into the equation is faster than solving algebraically. This is called backsolving and it is one of the techniques that distinguishes those who score 80+ in the section.

Manage time aggressively. If after 2 minutes you do not see the path, choose the best option and move on. One wrong question costs little; three unanswered questions at the end of the section cost a lot — the GMAT heavily penalizes missing answers.

Verbal Reasoning: 23 questions, 45 minutes

Verbal has only two question types: Reading Comprehension and Critical Reasoning. Sentence Correction has been eliminated. Everything is in English, of course — if your reading speed is not yet at the right level, a targeted English tutoring path focused on the GMAT can make the difference.

Reading Comprehension — passages of approximately 300-350 words with 3-4 questions each. Topics vary: natural sciences, business, social sciences. You don't need to know the topic — you need to understand the argument's structure. What thesis does the author support? What evidence does the author provide? Where is the reasoning weakest?

Critical Reasoning — one question, a short argument, five answers. You are asked to strengthen or weaken the argument, find the hidden assumption, evaluate the evidence. These questions are treacherous because four answers seem plausible — and the GMAT counts on that.

Average time: ~1 minute and 57 seconds per question. The pace is faster than Quant.

Three things that work:

Read for structure, not details. On RC passages, the first read should take 2-3 minutes and capture: main thesis, argument structure, author's tone. You look for details when a question asks for them — not before.

In Critical Reasoning, identify the conclusion before looking at the answers. It seems obvious, but under pressure many jump straight to the options. Take 15 seconds to formulate in your head "the author argues that X because Y" — then look for the option that attacks or supports that link.

Watch out for "almost right" answers. The GMAT always includes an option that is 90% correct but has one word or assumption that is off. The difference between a 75 and an 85 in Verbal is the ability to distinguish these nuances.

Data Insights: 20 questions, 45 minutes

The newest section and the one where most candidates prepare the least. Mistake. Data Insights weighs as much as the other two sections and has five different question types — the variety is the real obstacle.

The calculator is available only in this section. Use it — but don't overuse it. The calculator slows you down if you use it for calculations you would do faster mentally.

Specific strategies for each question type: GMAT Data Insights: Strategies for the Newest Section

The mistakes we see most often

The five most common GMAT preparation mistakes are: studying theory without practising under pressure, ignoring Data Insights until the last minute, failing to analyse errors by type (time, comprehension, knowledge), repeating simulations without reviewing them, and underestimating test day logistics. Avoiding them can shorten preparation by weeks.

Studying theory without practising under pressure. The GMAT is a performance test, not a knowledge test. Knowing the theory 100% and never having applied it with a timer running is like training for a marathon by reading a book about running. Exam-condition simulations should start from the second week of preparation, not the last. The Up to Ten method integrates practice under pressure from the very first sessions, precisely to avoid this mistake.

Ignoring Data Insights. Many candidates with quantitative backgrounds focus on Quant and Verbal and save the last few days for DI. This is a serious mistake: Data Insights weighs exactly as much as the other two sections, has the highest variety of formats, and Data Sufficiency requires a mental approach completely different from traditional problem solving.

Not analysing mistakes. Doing 10 simulations and only looking at the final score is a waste of time. Every mistake should be classified: was it a time error? Comprehension? Carelessness? Knowledge? The first three are solved with strategy. The last with study. Confusing them extends preparation by weeks.

Repeating the same questions. After completing a simulation, reviewing it and understanding the mistakes is worth as much as doing a new one. Many candidates accumulate "completed" simulations without ever going back. The Up to Ten platform tracks errors by question type and topic area, so the tutor calibrates the work exactly where it is needed.

Underestimating test day. Logistics: check-in takes 15-30 minutes. You cannot bring anything into the exam room — not even a watch. The environment is different from your home. If you have never simulated under uncomfortable conditions (noise, small desk, hard chair), you will lose points on test day for reasons unrelated to your preparation.

4-phase study plan

An effective GMAT plan unfolds in four phases: diagnostic (week 1), section-by-section foundations (weeks 2-5), integration with weekly full simulations (weeks 6-9), and final refinement (weeks 10-12). Duration adapts to your starting point, but the sequence remains the same for all profiles.

Phase 1 — Diagnostic (week 1)

Take a full official simulation (GMAC offers two free mock tests on mba.com). Don't prepare beforehand — the diagnostic score must be honest. Analyse results by section and question type.

Phase 2 — Foundations (weeks 2-5)

Work on one section at a time. For Quant: review theory where the diagnostic showed gaps, then do 20-30 questions per day in GMAT format. For Verbal: read one Financial Times or Economist article per day to build reading speed, then practice Critical Reasoning. For Data Insights: learn the five formats and practice each one specifically.

Phase 3 — Integration (weeks 6-9)

Full simulations: one per week, under exam conditions. Timer, no unscheduled breaks, no phone. After each simulation, 2 hours of error analysis. Between simulations, targeted practice on identified weak areas.

Phase 4 — Refinement (weeks 10-12)

Final 2-3 simulations to consolidate the score. Focus on time management and stress management. Strategy for section order and bookmark usage. The last week: no heavy studying, just light review and rest.

With a dedicated tutor, the phases overlap and adapt. The initial diagnostic on the Up to Ten adaptive platform identifies weak areas with greater precision than a generic mock, because it analyses not just the score but time per question, error patterns and trends over time.

Resources and materials

The essential GMAT preparation resources are three: official GMAC mock tests on mba.com (the most realistic), Manhattan Prep guides for theory, and an adaptive simulation platform that calibrates difficulty to your level. For Data Insights, specific material is still scarce: official GMAC resources remain the primary reference.

Official GMAC resources — the official mock tests on mba.com are the most realistic. Take at least 2 during preparation. The official Question Bank is the reference for question difficulty. You can find everything on the official GMAC preparation resources.

Reference books — Manhattan Prep guides remain solid for theory, even if updated to the current format. For Data Insights, material is still relatively scarce — official GMAC resources and direct practice are the best path.

Adaptive simulations — the difference between practising on static questions and doing simulations that adapt to your level is enormous. The Up to Ten platform uses IRT (Item Response Theory) algorithms — the same technology as the real GMAT — to calibrate difficulty in real time. This means every simulation is built for your current level, not a generic one.

FAQ

How much does the GMAT cost? The cost is $275 USD (approximately EUR 255) for the in-centre test and$300 for the online version with remote proctoring. For tutor preparation costs, check our pricing page. Registration is on mba.com. In Italy there are Pearson VUE centres in Milan, Rome, Turin and other cities.

How many times can I retake the GMAT? Up to 5 times in 12 months (with a lifetime maximum of 8 attempts), with a minimum interval of 16 days between attempts. With ScoreSelect you can choose which score to send to business schools — they will not see the attempts you don't send.

Is the GMAT in English? Yes, exclusively. There is no Italian version. All preparation must be in English. If your English is not fluent, add 4-6 extra weeks to build the reading speed needed for Verbal.

GMAT or GRE? Most European and American business schools accept both. The GMAT is preferable if you are targeting only MBA/management programmes — admissions consider it the "native" test of the field. The GRE makes sense if you are also considering non-business programmes (Master in Data Science, for example). For those considering Bocconi at the undergraduate level, the SAT is an alternative worth considering. When in doubt, take a diagnostic of both and choose where you have more room to grow.

Can I prepare on my own? You can, if you are disciplined and have a good starting level. But the difference between a 615 and a 665 — the points that matter for the best schools — is almost always a matter of strategy, not knowledge. A tutor who knows the test identifies error patterns in one session that would take you weeks to recognise on your own.

How does preparation with Up to Ten work? A dedicated tutor analyses your diagnostic, builds a personalised plan with weekly targets, and calibrates the path using data from the adaptive simulation platform. Every practice session is tracked in Up to Connect: score by section, time per question, weak areas, trends over time. You and the tutor see exactly where you are improving and where more work is needed.
