1. TRULY ADAPTIVE

The only mocks that replicatethe actual GMAT experience

Why? We reverse-engineered GMAT's exact algorithm through 200+ official simulations.

The result? Mocks that replicate the test, not just mimic it.

Test day? Just another practice session.

3X question pool visualization
3X Question Pool
Per Mock
Each mock draws from a question pool containing 3X the questions needed, ensuring we always have the right difficulty level ready—no matter how well or poorly you perform. When you ace 3 hard questions in a row, we serve an even harder 4th question, just like test day.
Never run out. Always the right difficulty.
Not just 3 but
5 Difficulty Levels
While most mock tests serve questions from three question banks—Easy, Medium, or Hard—SIGma-X mocks' question picking engine picks questions from 5 different question banks. The result? A more precise estimate of your ability.
Five levels. Smoother progression. Better targeting.
5 difficulty levels demonstration
Question-level adaptability visualization
Granular Adaptability
at Question-level
Our advanced question picker dynamically adjusts the complexity of the next question by analyzing not only your most recent response, but also how you have answered questions till that point. This method enables an exceptionally accurate assessment of your ability.
Real-time adaptation. Precise ability measurement.

2. NEVER RUN OUT

Practice until you're ready,Not until you run out

The mock scarcity problem is real. You buy a prep course, get 6 mocks, burn through 3 in the first month, then ration the rest. You're forced to choose between targeted section practice and saving mocks for milestones.

With SIGma-X, this problem doesn't exist. 70+ sectional mocks, 5 full-length mocks, separate databases. Practice as much as you need, not as much as your platform allows.

Sectional Mocks

  • 20+ Quant Sectionals
  • 20+ Verbal Sectionals
  • 20+ DI Sectionals

Need to work on Verbal? Take 5 Verbal section mocks. Quant weakness? Practice 10 Quant sectionals. With 20+ mocks per section (Quant, Verbal, DI), you'll never ration practice. Each sectional takes 45 minutes—perfect for targeted improvement without burning 2.5 hours on full-length tests.

Full-Length SIGma-X

  • 3X Question Pool
  • Feeds Sectional Database
  • Never Reduces Availability

Full 2.5-hour tests covering all three sections. Build test-day stamina and get complete score reports. Here's the key: Sectional and full-length mocks use separate question databases. Take 20 Quant sectionals without reducing your full-length availability. Never see repeated questions between sectional and full-length mocks.

3. DEEP ANALYTICS

Beyond Basic Score ReportsActionable Insights That Guide Your Prep

Most mocks give you a score and a vague "work on Quant" recommendation. That's useless. With SIGma-X see your performance broken down across subsections, difficulty levels, and individual topics—exactly which 2-3 weaknesses are costing you the most points.

Precision targeting. Maximum score gain.

Five Layers of Insight

That Pinpoint Exactly Where to Improve

  • Overall Score Estimate - Your Current Standing

    Where do I stand right now?

    • See your current estimated score with percentile ranking across Quant, Verbal, and Data Insights

    • Compare your performance against your target score to understand the gap

    • Example: "Current: 705 (98%ile). Target: 735 — You're 30 points away. Verbal needs the most work (V84 vs V88 target)"

  • Subsectional Scores - The Big Picture

    Which subsections drive my score?

    • See your performance across all GMAT subsections (Algebra, Geometry, CR, RC, MSR, TPA, etc.)

    • Understand exactly which areas are holding you back from your target score

    • Example: "You're at 82nd percentile in Two-Part Analysis but only 31st in Multi-Source Reasoning—focus your next week there"

  • Difficulty Breakdowns - The Scoring Reality

    Where am I losing points?

    • See your accuracy at Medium, Medium-Hard, and Hard difficulty levels

    • Understand the difficulty threshold where your performance drops

    • Example: "100% accurate on Data Sufficiency Hard questions, but only 33% on Multi-Source Reasoning—that's your growth zone"

  • Topic-Level Filtering - Surgical Precision

    What specific topics need work?

    • Drill down to individual topics within each subsection

    • Identify your exact weaknesses without guesswork

    • Example: "Filter by MSR + MH difficulty to see exactly which Medium-Hard Multi-Source Reasoning questions you missed"

  • Time Management Insights - Optimize Your Pace

    Am I rushing or spending too long?

    • Compare your time vs median time for each question with visual indicators

    • Identify 4 critical timing patterns: Excessive Time, Rushed Through, Timing Influence, and Luck Factor

    • Example: "Average time on correct answers: 2:22, on incorrect: 2:02—you're rushing through harder questions"

4. SCORE ACCURACY

Stop Guessing When You're ReadyKnow Your Actual Test-Day Score

You've scored 715 on your mock. But is it really a 715? Or could it be 685... or 755? With most mocks, you just don't know—so you never know if you're actually ready.

No more. With SIGma-X, your scores are accurate. Score 715? Expect 705-725 on test day. Finally know when you're ready to book that test.

My Mock Score Matched Exactly

My last mock was a 705, exactly what I scored on the test... SIGma-X mocks, it's not just about the score, it is about the kind of mistakes or the number of mistakes that you do and how it translates to a particular score... e-GMAT (SIGma-X mocks) I would say is more accurate than the official mocks itself.

Mocks Matched My Final Score

My favorite part would be mocks without a doubt... with mocks you're just trying to understand how would I manage my time and what score I would get... sectional mocks as well I was getting around those scores like 85, 86 and then you know like in test center got to 87 as well.
