What This Tests

Data Sufficiency is unlike anything you have seen on the SAT, ACT, or any other standardized test. The question is not “what is n?” — it is “do I have enough information to know whether n is odd?” That distinction is the entire game.

On test day you have to fight the instinct to grab a calculator and start solving. Instead, the EA wants you to look at each statement and ask one binary question: does this alone narrow n down to a single parity, or does it leave room for both?

Real executives make this judgment call every day — you rarely have all the data you would like, and the skill that matters is recognizing when you have enough to act. Data Sufficiency is the EA’s clean test of that exact discipline.

Test-Day Decision

The rule to apply

For every DS statement, ask one question: “Does this alone force a single answer to the prompt — yes or no?” If yes, sufficient. If both answers remain possible, insufficient. Never combine statements until you have evaluated each one alone.

Why this works: Data Sufficiency rewards binary thinking, not algebra. The trap is to grab both statements together and try to “solve harder.” Instead, isolate each statement and treat the other as if it does not exist. Only if both fail individually do you check whether they help when combined.

Most candidates lose points on DS not because the math is hard, but because they skip this discipline. The format is testing process, not arithmetic.

Full Solution

The key insight: you are not solving for n. You are asking one question per statement: “Does this alone force n to be odd — with zero ambiguity?”

→Statement (1): n² is odd.

n² is odd tells us something powerful: squaring preserves parity. Odd numbers stay odd when squared. Even numbers stay even when squared. So if the result (n²) is odd, the input (n) must have been odd too. Statement (1) alone answers the question: yes, n is odd.

n = 2 even→n² = 4 → even✗

n = 3 odd→n² = 9 → odd✓

n = 5 odd→n² = 25 → odd✓

Statement (1) alone is sufficient.

→Statement (2): n + 1 is even.

n + 1 is even means n is one step below an even number. One step below even is always odd.
4 is even → 3 is odd.
6 is even → 5 is odd.
8 is even → 7 is odd.
The pattern holds without exception. Statement (2) alone answers the question: yes, n is odd.

n = 2 even→n + 1 = 3 → odd✗

n = 3 odd→n + 1 = 4 → even✓

n = 5 odd→n + 1 = 6 → even✓

Statement (2) alone is sufficient.

Both statements independently confirm n is odd. When each statement alone is sufficient, the answer is always D

Trap Breakdown

✗

Trap C — “Both together”
The most tempting wrong answer. Candidates default to “use both” because it feels safer, but each statement here is independently sufficient. Picking C means you skipped the discipline of evaluating each statement alone.

✗

Trap A or B — “Only one alone”
You tested one statement, found it sufficient, and stopped. The error is missing that the other statement encodes the same constraint through different math. n² odd and n+1 even are two ways of saying the same thing.

✗

Trap E — “Not even together”
You did not see how either statement pins down parity. The fix is to memorize three rules: even² is even, odd² is odd, and odd + 1 is even. With those, both statements become trivially sufficient.

Why candidates choose EA PrepPro

Not GMAT content with geometry removed.
Built for the EA from scratch.

Most EA prep is GMAT material with a few pages removed. EA PrepPro was built from the ground up — every question, every explanation, every format decision made for experienced professionals short on time.

Your second module gets harder only if you earn it

Module 2 difficulty is determined by your Module 1 performance — closely mirroring the EA's adaptive structure. Score 4+ in IR M1 and you're routed to the harder set. Underperform and you get a more accessible set. Exactly how the stakes work on test day.

No going back. 30 minutes. No exceptions.

Each section runs on a strict 30-minute clock. Questions appear one at a time with no backtracking — closely reflecting the EA's time pressure. Pause is available for Tutor Mode; Exam Mode runs uninterrupted.

Every IR format the EA uses

Multi-Source Reasoning with intentionally contradicting source tabs. Two-Part Analysis requiring multi-step logic. Sortable Table Analysis with boundary conditions. Graphics Interpretation with real SVG charts. All four formats, at the right difficulty level.

Explanations that teach, not just correct

Every question has 7 structured explanation layers: why the EA tests this skill, the test-day decision rule, a fast strategy with step-by-step reasoning, the full worked solution, why each wrong answer is tempting, the pattern to recognize next time, and a one-line rule to carry into the exam.

Zero specialist knowledge required

No geometry with π. No PE waterfall models. No SaaS metrics. Every question is solvable using logic and the data given — no external knowledge assumed. If it's not in the question, it's not needed to answer it.

Every official EA mechanic, faithfully recreated

On-screen calculator that appears only during Integrated Reasoning — exactly like the real test. Review screen at the end of each module so you can revisit and change answers before locking in. Free navigation within a module, no navigation between them. Instant module-to-module transitions, just as GMAC delivers them on test day. Practice the real experience, not a GMAT substitute.

Two Modes. One Goal.

Study when you're learning.
Simulate when you're ready.

Every exam ships with both modes. Tutor Mode teaches the pattern; Exam Mode tests whether you've internalized it. Switch freely, practice strategically.

Tutor Mode

Learn the reasoning behind every answer

Designed for when you're still building patterns — not when you're ready to test yourself.

Instant feedback, inline See Correct or Incorrect the moment you answer, with the full 7-layer explanation right there — not after a 90-minute wait.
Linear progression One question at a time. Next appears after you answer. No navigating back — you learn from this question before moving on.
Module completion screens After each module, a summary screen with your score, a clear "Module complete" marker, and a deliberate "Begin Module 2" button so you can pause and reset.
Calculator always on in IR Draggable, on-screen calculator available throughout Integrated Reasoning — identical to what you'll have on test day.
No pressure, no locking Take your time. There's no module submit that locks you out. The goal here is understanding, not timing.

Best for: Your first 2–3 weeks of prep. Learning question formats, building intuition for traps, understanding why each wrong answer is tempting.

Exam Mode

Simulate test day, down to the timer

Designed for the final stretch — when you need to know if you'll actually perform under pressure.

No feedback during the exam Results come at the end, not after each question. Just like the real EA — you have to commit without knowing whether you got it right.
Free navigation within a module Previous, Next, skip, and come back — anywhere inside the current module. Flag tough questions for review. Exactly the navigation the real EA gives you.
Review screen before every submit Before you lock a module, see every question's status — answered, flagged, unanswered. Jump back to any of them. Submit only when you're sure.
Module locking, no going back Once you submit a module, answers are final. The next module begins instantly — the same irrevocable commitment the real exam demands.
CSV export of every attempt Download your full results — question by question, timing, accuracy — and load them into the Performance Tracker to analyze trends across exams.

Best for: The last 1–2 weeks before your real test. Building stamina, calibrating your pace, surfacing which question types still break down under pressure.

Switch modes any time. Every exam in every plan ships with both. Most candidates run Tutor first, then the same exam again in Exam Mode once they're ready to test themselves.

How it works

From baseline to test day
in four steps

Most candidates follow this path. Some skip steps once they know their weak points — but the structure is what gets you exam-ready in weeks, not months.

Establish your baseline

Start with the free exam or the Diagnostic plan. See where you stand across all three sections before you commit to a prep plan. Fifteen minutes to know if you're already close — or how far you have to go.

Learn patterns in Tutor Mode

Work through your first exam in Tutor Mode. Instant feedback after each question with the full 7-layer explanation. No timer, no pressure — this is where you build intuition for traps and question types.

Simulate in Exam Mode

Once the patterns click, run a full exam under real conditions. Thirty-minute timer per section, adaptive Module 2 routing, review screens before each submit. This is where you learn whether you’ll actually perform under pressure.

Fix weak spots with the Tracker

Export your CSV, load it into the Performance Tracker. It tells you exactly which question type is costing you the most points and jumps you to those questions in Question Review. Fix the pattern, then run the next exam.

Two to four weeks. Four exams. One test-day-ready candidate.

Performance Tracker

See your progress.
Fix your weaknesses.

Every exam exports a CSV of your results. Load them into the Performance Tracker to see exactly where you're losing points, what patterns of error repeat, and how you're trending across attempts.

About the Exam

What is the Executive Assessment?

A 90-minute admissions exam for experienced professionals. Shorter than the GMAT, different in scope, and accepted by top EMBA programs worldwide.

The Executive Assessment (EA) is created by GMAC — the same organization behind the GMAT — but it's built for a completely different candidate. While the GMAT targets recent graduates, the EA is designed for professionals with 8–15 years of experience who are applying to Executive MBA programs at schools like INSEAD, London Business School, and Wharton. (EA PrepPro is not affiliated with GMAC.)

The EA is shorter and more focused than the GMAT. There's no essay, no geometry with π, and no prolonged prep required. The exam assumes you already have real-world analytical experience — it tests whether you can apply it quickly under pressure.

Scores range from 100 to 200, with each of the three sections contributing equally. Most top EMBA programs look for a total score above 155, though requirements vary by school.

Test Strategies

4 strategies that separate high scorers from the rest

The EA rewards strategic thinking over brute-force calculation. Here's what separates high scorers from the rest.

Integrated Reasoning

Check all tabs before answering any MSR question

Multi-Source Reasoning questions are designed so that the answer requires combining — and sometimes reconciling — information from multiple tabs. Candidates who answer from a single source almost always fall into the trap the test-makers set. Spend 90 seconds reading all three tabs before touching the answer choices.

Verbal Reasoning

Find the conclusion before evaluating answer choices in CR

Critical Reasoning questions hinge on the argument's conclusion — not its premise. Before reading the answer choices, identify the conclusion in one sentence. Then ask: which answer choice directly strengthens or weakens that specific claim? Candidates who skip this step waste time evaluating choices that address the wrong part of the argument.

Quantitative Reasoning

Test edge cases in Data Sufficiency — zero, negatives, fractions

A statement that works for positive integers may fail for zero, negative numbers, or fractions. The EA frequently uses these edge cases to make a statement appear sufficient when it isn't. Before marking a DS statement as sufficient, always ask: does this hold if the variable is zero? Negative? A fraction between 0 and 1?

General Strategy

Use the adaptive engine to your advantage in Module 1

Your Module 2 difficulty depends entirely on your Module 1 score. The thresholds are 4/6 for IR and 5/7 for Verbal and Quant. If you're on the Hard track, you'll face harder questions but the scoring rewards you for it. Don't rush Module 1 — it sets the ceiling for your entire section score.

FAQ

Common questions

Is EA PrepPro affiliated with GMAC or the official EA?

No. EA PrepPro is a fully independent preparation product with no affiliation to, endorsement by, or association with GMAC. This product does not use or reproduce any official GMAC questions or content. All practice questions are 100% original, created independently to reflect the EA's format, structure, and difficulty level.

How is this different from GMAT prep materials?

The EA has no geometry, a different question distribution, fewer total questions, and a shorter time limit. Most GMAT materials are adapted rather than built from scratch for the EA. Every question in EA PrepPro was designed specifically for the EA's format — no π, no specialist financial knowledge required, and question difficulty calibrated to the EA's actual level.

How long do I need to prepare for the EA?

Most candidates prepare in 2 to 4 weeks with 1 to 2 hours of focused daily practice. The Standard plan covers that window with 4 exams. If you're targeting a highly competitive EMBA program or haven't practiced formal reasoning in a while, the Intensive plan gives you more exposure to question patterns.

Can I use it on my phone or tablet?

Yes. The exams work on any device with a modern browser — desktop, tablet, or mobile. That said, we recommend using a laptop or desktop for the actual exam practice to simulate real test conditions as closely as possible.

What's the difference between Tutor Mode and Exam Mode?

Tutor Mode is a study environment. You answer one question at a time, get instant feedback with the full 7-layer explanation, and move forward linearly — no going back, no timed pressure, no module locking. Use it to learn patterns. Exam Mode simulates the real EA: no feedback during the exam, free navigation within each module (Previous / Next / flag / review), a review screen before every module submit, and once you submit, the module locks and the next one begins instantly. Results come at the end. Both modes ship with every exam, and you can switch at any time. Most candidates run Tutor first, then repeat the same exam in Exam Mode once they're ready to test themselves.

How faithful is Exam Mode to the real EA?

As faithful as an independent product can be. You get the on-screen calculator in IR only (drops away when you enter Verbal and Quant). Review screens at the end of each module with a grid of answered, flagged, and unanswered questions. Module locking on submit. Instant module-to-module transitions, no "loading" pauses. Adaptive routing to Medium or Hard Module 2 based on Module 1 performance. 30-minute timer per section. What we deliberately don't do: there's no score range 100–200 output because only GMAC controls the official scale. Instead, you get weighted-points performance and tier categories (Excellent, Competitive, Developing, Needs Work) calibrated to how the real test behaves.

What does the Performance Tracker actually do?

It turns your exam results into a study plan. Every exam exports a CSV when you finish. Load one (or several) into the Performance Tracker and it gives you four views: an Overview with your weakest section and a concrete next action, Question Review with every question sortable and filterable, Error Patterns that highlight the dominant type of mistake you're making and jump you straight to those questions, and Compare Exams that shows whether you're actually improving across attempts. It also tracks a countdown to your test date with exam-pacing recommendations. The Tracker is included in every plan — no extra cost.

Are the explanations actually useful or just answer keys?

Each explanation has 7 structured sections: what the question tests and why the EA includes it, the test-day decision rule, a fast strategy with step-by-step reasoning, the full worked solution, a breakdown of each wrong answer and why it's tempting, a pattern to recognize in future questions, and a one-line takeaway rule to remember on test day. The goal is that you never make the same mistake twice.
