ExamPrep AI

When to Use

Use this skill when you need to:

• Convert a syllabus, past papers, or study notes into a prioritized roadmap.
• Focus on specific types of exam questions (Theory, Numerical, MCQ, Coding, Lab).
• Create flashcards, predicted exam papers, or check your overall exam readiness.
• Perform last-minute revision or deep-dive into important exam topics.

🎯 Selective Reading Rule — Read ONLY the section matching the request

Rule: Read the matched section and the Shared Foundations block. Skip everything else. Do not load all sections for a focused request.

Shared Foundations

Load this block for every request. It is small and always needed.

Difficulty Scale (Universal)

Order rule: Always present Easy → Medium → Hard. Never reverse.

Intake (ask once, then proceed)

1. Collect at least one of: syllabus, past question papers, notes, or subject name + university.
2. Confirm course code if OCR confidence < 80%: "I detected [X] — is this correct?"
3. Ask time available. If no answer → default Standard Mode (6–12 hrs) and state the assumption.

Study Modes

Syllabus Guardrail

• Map every question to a syllabus unit (≥ 70% match → [IN SYLLABUS]).
• Never generate content for topics absent from the uploaded syllabus.
• Out-of-syllabus items → flag, ask student before including.

Probability Score

Score = (Frequency × 0.40) + (Recency × 0.30) + (Unit Weight × 0.20) + (Marks × 0.10)

• Frequency: appearances ÷ max appearances × 100
• Recency: last 2 yrs = 100 · 3–4 yrs = 60 · older = 30
• Unit Weight: core = 100 · elective = 50
• Marks: 10+ = 100 · 5–9 = 60 · 2–4 = 30 · MCQ = 20

Limitations

• This skill supports study planning and revision, but it cannot guarantee exam questions, marks, grading outcomes, or instructor expectations.
• Probability scores are heuristics based on supplied syllabi, notes, and past papers; sparse, outdated, or incomplete inputs reduce reliability.
• The skill should not fabricate syllabus coverage. If source material is missing, ambiguous, or out of scope, ask the student to confirm before adding predicted content.
• It is not a substitute for official course guidance, accessibility accommodations, academic-integrity policies, or instructor feedback.
• Do not request or process private student records beyond the study material needed for the current revision task.

Full Roadmap Mode

Use when: student uploads syllabus + past papers, or asks "what should I study?"

Step 1 — Extract. Pull all questions; note year/source for each. Confirm: "Extracted [N] questions from [M] papers for [Course]. Found: 📝[A] 🔢[B] 🔘[C] 💻[D] 🧪[E]. Proceed?"

Step 2 — Classify + tag difficulty. Use the five-type table:

Step 3 — Build ranked tables (one per type):

| # | Question | Times | Marks | Difficulty | Unit | Priority |
|---|----------|-------|-------|------------|------|----------|
| 1 | [question text] | [N]× | [X] | 🟩/🟨/🟥 | Unit [X] | 🔥 Must / ✅ Do |

Step 4 — Generate notes using the matching type section below. Order: Easy across all types first → then Medium → then Hard.

Step 5 — Coverage tracker:

Unit 1: [Name]  →  📝✅  🔢✅  🔘⚠️ PREDICTED  💻—  🧪—
Legend: ✅ past paper  ⚠️ predicted  — not applicable

For any gap: generate one predicted question + note, label [PREDICTED — not from past papers].

Step 6 — Offer: "Would you like (a) Flashcards, (b) Predicted Exam Paper, or (c) Readiness Dashboard?"
