The 20-question diagnostic at the start of PSCPrep.ai isn't a warm-up or a placeholder. It's the seed for your first AI-generated weekly plan. Here's how we pick the questions, what we measure, and how that map turns into your schedule.
How we pick the questions
Syllabus coverage + difficulty spread
We sample across the exam syllabus (Polity, History, Geography, Economy, Science, CA, Reasoning) so that no single topic dominates. Each question is tagged by topic and difficulty (easy / moderate / tough). The mix is fixed so we get a comparable baseline for every user — not random.
What we measure
Accuracy by topic, time, and weak spots
- Correct vs incorrect per topic — so we know where you're strong and where you're not.
- Time per question — fast and wrong suggests guessing; slow and wrong suggests concept gaps.
- We don't use the diagnostic to rank you. We use it to allocate time in your first week: more time on weak topics, less on strong ones.
How it becomes your first plan
Topic weights and session allocation
We map your topic-wise accuracy to syllabus weightage (e.g. from PYQ analysis). Topics where you scored below a threshold get more sessions and more PYQs in the first two weeks. Topics where you did well get maintenance slots. As you take mocks later, the plan keeps updating — the diagnostic is just the first input.
Key takeaways
- · 20 questions, syllabus-wide and difficulty-balanced. Comparable baseline for everyone.
- · We measure accuracy by topic and time per question to flag weak areas and guessing.
- · Your first weekly plan is built from this — more time on weak topics, then the plan adapts with mocks.
