Prelims is multiple-choice — you know instantly if you're right. Mains is descriptive — without a teacher reviewing your answers, you can write for months without knowing whether your structure, content, or examples are actually good enough. The Answer Evaluator fixes that.

The mains feedback problem

No feedback loop = no improvement loop

Most aspirants write answers, review them vaguely, and repeat. Without specific feedback on what's missing — a missing constitutional article, a weak conclusion, no examples — they improve slowly or not at all. The Answer Evaluator gives you the specific feedback that teachers give, instantly, without a booking or a wait.

What the evaluator scores

Three dimensions, one score

Structure

Intro → body → conclusion flow, paragraph organisation, word count alignment

Content Depth

Key facts, relevant acts/articles, data points, constitutional provisions cited

Examples & Data

Relevant case studies, statistics, schemes, or historical examples included

How to read the improvement bullets

Specific, not generic

Each improvement bullet is specific to your answer. Not "add more examples" — but "cite the 73rd Constitutional Amendment for Panchayati Raj — it's the statute examiners expect here." Not "improve your conclusion" — but "your conclusion restates the intro. Rewrite it to include a forward-looking policy recommendation."

The goal is to fix the next attempt, not just grade the current one.

Instant scores on all three dimensions — plus improvement bullets that are specific enough to act on.
Best practice: evaluate 2–3 answers per day. The real improvement comes from the iteration loop: evaluate → read the bullets → rewrite the answer → compare. If you just evaluate and move on without rewriting, you're losing half the value.

Supported exams and question types

Works for short notes (150 words) and long-form essays (250–500 words). Paste any mains question + your answer; the evaluator calibrates expectations to the question type and word limit.
