All mistakes are not the same.

Solving more questions won’t fix a sign flip, and slowing down won’t fix a concept gap. Distinct failures need distinct fixes.

  • Concept gaps

    You forgot the formula parameters or misapplied the core physical theory.

    • Concept gap
    • Concept confusion
    • Formula error

    The cureRevisit the fundamentals.

  • Application gaps

    You understood the theory but couldn’t set up the mathematical equations.

    • Mis-modelled
    • Multi-step breakdown
    • Edge case missed

    The cureVaried modelling practice.

  • Execution slips

    Arithmetic errors, sign flips, or silly calculation mistakes under stress.

    • Calculation error
    • Unit/sign error
    • Silly mistake

    The cureReview your step layouts.

  • Strategic mistakes

    Misreading terms, rushing, panic under the clock, or second-guessing correct options.

    • Misread question
    • Time pressure
    • Overthought
    • Did not attempt

    The cureTemperament testing.

How JEE Sniper works

We remove the tedious paperwork of logging. Capture a mistake in seconds, tag the cause, and get weekly AI Mentor Reviews.

  1. Snap and OCR pre-fill

    Upload a screenshot of the question you missed. AI reads the image and pre-fills the problem details, options, difficulty and subject.

  2. Core categorization

    Choose which JEE gap caused the failure, then add a sentence in your own words explaining the mistake. The habit builds metacognitive checking.

  3. AI Mentor Reviews and charts

    Generate AI Mentor Reviews of your test history. They highlight your exact conceptual bottlenecks and give you a study roadmap you can act on.

Why did you get it wrong?Try it. This is the real checklist.

1 root cause tagged under Concept gap.

See where the marks go.

Every logged error feeds your charts, so the pattern behind a bad mock is visible by subject, by category and by week.

The physics of mistake classification.

Read our core analysis on why “I’ll be more careful next time” is a mathematically flawed study strategy, and how naming your failure modes directly impacts mock test percentiles.

Solving 10,000 problems teaches you 10,000 answers. Understanding why you got a hundred of them wrong teaches you how your mind actually fails.
