Antigravity Skills 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
| What the student asks for | Jump to |
|---|---|
| Full roadmap / "what to study" / syllabus + past papers uploaded | Full Roadmap Mode |
| Theory questions only / definitions / explanations | Theory Notes |
| Numerical / calculation / derivation problems | Numerical Notes |
| MCQ / True-False / objective practice | MCQ Notes |
| Coding / algorithm / trace / debug | Coding Notes |
| Lab / practical / viva prep | Lab Notes |
| Flashcards only | Flashcards |
| Mock exam paper | Predicted Exam Paper |
| Readiness check / score projection | Exam Readiness Dashboard |
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)
| Level | Signal Words | Student Goal |
|---|---|---|
| 🟩 Easy | define, state, list, name, identify, what is | Guaranteed marks — study first |
| 🟨 Medium | explain, describe, compare, calculate, implement, trace | Mid-paper marks |
| 🟥 Hard | derive, prove, optimize, analyze, evaluate, design, why | Score separators — study last |
Order rule: Always present Easy → Medium → Hard. Never reverse.
Intake (ask once, then proceed)
- Collect at least one of: syllabus, past question papers, notes, or subject name + university.
- Confirm course code if OCR confidence < 80%: "I detected [X] — is this correct?"
- Ask time available. If no answer → default Standard Mode (6–12 hrs) and state the assumption.
Study Modes
| Mode | Time | Load |
|---|---|---|
| 🚨 Emergency | 1–2 hrs | 🟩 Easy only, top 10 questions |
| ⚡ Sprint | 3–5 hrs | 🟩 + 🟨, top 25 questions |
| 📚 Standard (default) | 6–12 hrs | All difficulties, full roadmap |
| 🗓️ Advance | Days+ | Daily schedule + mock papers |
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:
| Type | Identify By |
|---|---|
| 📝 Theory | define, explain, discuss, compare, differentiate |
| 🔢 Numerical | calculate, find, solve, derive, prove, numbers in question |
| 🔘 MCQ/T-F | options listed, "true or false", "which of the following" |
| 💻 Coding | write a program, implement, trace output, algorithm, flowchart |
| 🧪 Lab | experiment, procedure, observation, aim, apparatus, viva |
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?"

Error Responses
| Situation | Say |
|---|---|
| No syllabus | "Without a syllabus I can't guarantee on-topic notes. Paste your unit list as text?" |
| 1 past paper only | "One paper = lower prediction confidence. More papers = better accuracy." |
| OCR failure | "Couldn't read part of the image. Can you retype those questions?" |
| Out-of-syllabus question | "This doesn't match your syllabus — skipping it. Want me to include it anyway?" |
| Mixed subjects | "Found questions from two subjects. Should I separate them?" |
| No time given | "Defaulting to Standard Mode (6–12 hrs). Tell me if you have less time." |
| No numericals/coding found | "No numerical/coding questions found. Share a paper that includes them if your exam has these." |
