description	Emergency exam preparation system for ANY university worldwide. Generates ultra-compressed study plans for 12-hour, 6-hour, 3-hour, and 1-hour timeframes. Uses rapid memory encoding techniques (memory palace, chunking, peg system, acronym chains) for maximum retention in minimum time. Covers ALL subjects, ALL exam types.

Universal Last-Minute Crammer

Overview

When time is critically short, this skill provides the highest-yield study path. Uses cognitive urgency principles and memory encoding techniques to maximize what can be retained and recalled under time pressure. Not a substitute for proper study -- a rescue system for emergencies.

How This Skill Works

1. User provides: Exam time remaining (1h / 3h / 6h / 12h), subject, topics, exam format, current knowledge level
2. System selects: Ultra-high-yield topics only (based on PYQ frequency and weightage)
3. System designs: Minute-by-minute plan with memory encoding techniques
4. System generates: Condensed reference sheet and rapid-review materials
5. System provides: Exam-time strategies (time management, question selection, answer structure)

1. Timeframe Plans

Active Recall	30 min	Write everything from memory; fill gaps by checking notes

1-Hour Plan

Phase	Duration	Activity
Topic Selection	5 min	Identify 1-2 most important topics
Speed Read	20 min	Read condensed notes/textbook summaries
Memory Encoding	15 min	Create 1-page cheat sheet with key formulas/definitions (mental)
Active Recall	20 min	Close everything; recite/write key points from memory

2. Rapid Memory Encoding Techniques

Technique	How It Works	Best For	Example
Acronym Chain	First letter of each item forms a word	Lists, sequences, ordered steps	OSI Model: "Please Do Not Throw Sausage Pizza Away" (Physical, Data Link, Network, Transport, Session, Presentation, Application)
Memory Palace	Visualize walking through a familiar location; place items at specific spots	Structured collections of facts	Place networking concepts in rooms of your house: living room = Physical layer, kitchen = Data Link...
Chunking	Group information into meaningful 3-5 item chunks	Large amounts of structured data	Group sorting algorithms by complexity: O(n^2): Bubble, Selection, Insertion; O(n log n): Merge, Quick, Heap
Story Chain	Create a narrative connecting facts	Unrelated items, sequences	"The process (Ready) went for a run (Running) but got tired and waited (Blocked) for a bus, then was ready again (Ready)"
Visual Peg System	Associate each item with a numbered visual peg (1=gun, 2=shoe, 3=tree...)	Ordered lists, numbered items	1=gun (process creation needs a "bang"), 2=shoe (IPC needs a "pair")...
Spaced Micro-Reviews	Review at 10-30-60 minute intervals	Preventing decay in ultra-short timeframes	After learning a topic, test yourself at 10 min, then 30 min, then 1 hour

3. High-Yield Topic Identification

Selection Criteria (weighted)

Criterion	Weight	Description
PYQ Frequency	40%	How often has this topic appeared in past exams?
Marks Weightage	25%	How many marks does this topic carry?
Prerequisite Status	20%	Is this foundational for other topics?
Difficulty	15%	How quickly can it be learned? (easier = higher yield for cram)

Decision Matrix

PYQ Frequency	Marks Weightage	Easy to Learn?	Verdict
High	High	Any	MUST LEARN (highest priority)
High	Low	Yes	LEARN (quick win)
Low	High	Yes	LEARN (high marks per hour)
High	Low	No	SKIP (low marks for high effort)
Low	Low	Any	SKIP (not worth it)

4. Condensed Reference Sheet Format

Generated automatically for any subject in this format:

=== SUBJECT: OPERATING SYSTEMS ===

UNIT 1: PROCESS MANAGEMENT [HIGH YIELD - 40% weightage]

Process States: New -> Ready -> Running -> Waiting -> Ready -> Terminated
  KEY: Ready Queue holds processes waiting for CPU
  KEY: Context Switch = saving/restoring state on CPU switch

CPU Scheduling:
  FCFS: First come first served (convoy effect)
  SJF: Shortest job first (optimal avg wait, starvation risk)
  Round Robin: Time quantum q (q too small = context switch overhead)
  Priority: Preemptive/non-preemptive (starvation for low priority)

KEY FORMULA: Avg Waiting Time = sum(WT_i) / n

Synchronization:
  Critical Section Problem: Mutual Exclusion, Progress, Bounded Waiting
  Semaphore: S = resource count; wait(S) decrements, signal(S) increments
  Deadlock: Mutual Exclusion + Hold & Wait + No Preemption + Circular Wait
    -> Prevention: Break any one of the four conditions

5. Exam-Time Strategy (for the exam hall)

Situation	Strategy
Blank mind reading question	Start writing anything related; recall triggers from memory palace
Don't know first few questions	Skip them; answer what you know to build momentum
Running out of time	Write bullet points instead of full sentences; examiners award marks for keywords
Essay question, limited knowledge	Structure: Introduction + 2-3 points you do know + Conclusion. Never leave blank.
Numerical problem	Write the formula first (gets partial marks), then attempt the calculation
Recall a formula	Trace memory palace path in your mind
Excess time remaining	Review and expand your answers; add examples, diagrams, and cross-references

6. Cram-Friendly Output Formats

Format	Use	Time to Read
Single-Page Cheat Sheet	Mental key points + formulas	2 min
Rapid Revision Notes	3-5 page condensed subject summary	10 min
Audio Summary	Listen during travel/breaks	5-15 min
Flashcard Deck (Cram Mode)	20-50 high-yield cards only	5 min

7. Sleep Optimization & Stress Management

Sleep-Study Trade-Off

Research shows that sleep deprivation directly impairs the cognitive functions needed for exam performance — memory consolidation, attention, and executive function.

Sleep in 24h Window	Cognitive Effect	Recommendation
< 2 hours	Severe impairment — negates most study gains	Avoid. Study gains lost to cognitive deficit.
3-4 hours	Moderate impairment — reduced recall, slower thinking	Minimum viable for 12h cram window
5-6 hours	Mild impairment — acceptable for short-term exams	Target for multi-day cram sessions
7+ hours	Full cognitive function	Always preferred when time allows

Rule: Even in a 12-hour cram window, allocate 3-4 hours for sleep. The memory consolidation that occurs during sleep is more valuable than 3-4 additional hours of study.

Stress Management Techniques

Box Breathing (4-4-4-4)

Inhale (4 sec) → Hold (4 sec) → Exhale (4 sec) → Hold (4 sec)
Repeat 4-5 cycles. Use before entering exam hall or when anxiety spikes during exam.

5-4-3-2-1 Grounding

When panic or blank-mind sets in during the exam:

• 5 things you can see
• 4 things you can touch
• 3 things you can hear
• 2 things you can smell
• 1 thing you can taste

Positive Self-Talk Scripts

• Before exam: "I have prepared what I could. I will write what I know."
• Blank mind: "This is normal adrenaline. I will start with what I know and come back."
• Tough question: "Partial marks come from trying. I will write related concepts."
• Running out of time: "Bullet points earn marks. Keywords over sentences."

Exam Hall Toolkit Checklist

Before leaving for the exam, verify:

• Pen (primary) — gel or ballpoint as permitted
• Pen (backup) — spare ink refill or additional pen
• Analog wristwatch (not smartwatch — usually prohibited)
• Water bottle — transparent, label removed
• Government-issued photo ID / hall ticket
• Admit card / exam entry pass
• Simple calculator (if permitted for the subject)
• Geometry box / scale (for diagram questions)

Session Config

This skill integrates with the session config system (deps/session-profile.json). Before executing, check for an existing session profile:

• If deps/session-profile.json exists, read university, subject, pattern, and exam_type fields to auto-configure the skill.
• If the file does not exist, fall back to user-provided context or prompt the user to run setup-exam-prompt (or npm run init) first.
• Session config eliminates redundant context detection — detection happens once and is reused across all skill calls.

Error Handling

Situation	Action
Timeframe not specified	Default to 12-hour plan and ask user to confirm or specify
Subject/topics not provided	Respond: "Please specify the subject and topics you need to cram."
Insufficient time for requested scope	Suggest reducing scope: "3 hours is not enough for 5 units. Recommend focusing on 2 highest-weightage units."
User health concern (sleep deprivation)	Warn: "Sleep below 2 hours impairs cognitive function. Study gains may be negated. Recommend minimum 3-4 hours sleep."

Quality Gate — Check Before Output

• Timeframe matches plan generated (1h / 3h / 6h / 12h)
• Condensed reference sheet is included
• Active recall / self-test step present in plan
• Memory encoding technique assigned to each topic block
• Exam hall strategy section present
• Sleep recommendation aligned with timeframe
• No topic exceeds 1 page in the reference sheet (enforces conciseness)
