Trust the Spec, Not the Teacher

"The spec is the source of truth. Your teachers are one interpretation; the exam board is the other. When they disagree, the exam board wins every time."

Your exam is marked against the official specification, not your classroom notes. If the spec says you need to know X and your teacher skipped X, you'll lose marks — unless you self-teach X using the Spec Coverage tool.

Teachers make choices: what to prioritise, what to rush through, what to skip because they ran out of time. Those choices are not the exam. The exam is the whole spec. Every bullet point. Every keyword. Every sub-sub-section.

There is only one cure for blind spots: audit the spec yourself, subject by subject, bullet by bullet. Mark what's been taught, what you're shaky on, and what's blank. Then close the gaps with the Loop and the Confidence Engine.

01Audit — Use the Spec Coverage page to walk every spec point in Biology, Chemistry, and Geography.

02Flag — Mark anything untaught, unsure, or at blank confidence as RED.

03Close — Push the gaps into the Weakness Engine. Run the Loop on them. Prove them in the Confidence Engine.

04Retest — Revisit in 3–5 days. If it holds, it's yours. If not, loop it again.

The Loop

Every session, every topic, every time. Six phases. No shortcuts.

1 · Recall→ 2 · Repair→ 3 · Apply→ 4 · Mark→ 5 · Analyse→ 6 · Retest

Recall — Blank page. Dump everything before touching notes. This is where truth lives.
Repair — Fill the gaps you just exposed. Rebuild the knowledge cleanly, in your own words.
Apply — Real exam question. Exam conditions. Timer on.
Mark — Mark scheme or Claude. Be brutal. No "I basically said that" bullshit.
Analyse — Tag the error. Memory? Vocab? Structure? Timing? Careless? Misread?
Retest — Schedule the revisit 2–4 days later. Never just "move on".

The Pre-Recall Lock

Before you attempt any new topic, lock the foundation in place:

013 stats — named, numbered, dated. Not "about a million". 1.1m displaced, 2022.

021 counter-argument — the other side of the debate, the alternative view.

031 synoptic link — what does this topic connect to across the spec?

041 judgement starter — "Overall, the evidence suggests…" / "The most significant factor is…"

What wins marks · what loses them

✓ Wins

Named case studies with specific stats
Precise spec vocabulary used correctly
Clear evaluation with judgement
Counter-arguments handled
Synoptic links across topics
Structure: PEEL, signposted
Answering the actual question asked

✗ Loses

Vague generalisations ("many countries")
Wrong or missing key terminology
Description without evaluation
Single-sided arguments
Ignoring the command word
Running out of time on essays
Writing everything you know, not what's asked

Hell Week Rules · 8–16 June

🔥 Consolidation only

5 exams in 9 days. The margin is gone. Rules:

No new content. Period. Not even "just one more topic".
Retrieval drills only — flashcards, blurt-sheets, past questions.
Max 90 minutes per revision block. Then break. Walk. Drink.
Sleep is a revision tool. 8 hours, lights out 22:30.
Morning: 20 min retrieval on that day's exam topic. Evening: rest.
Between papers: decompress, walk, eat, sleep. Don't discuss the last paper.
Trust what's already in your head.

Supplement protocol

When	What	Why
Morning with oats	Creatine 5g	Cognitive performance, learning, memory
T-45 before a paper	Caffeine 100mg + L-theanine 200mg	Alertness without jitter
Never after 14:00	Stop all caffeine	Protects sleep — sleep wins exams
Daily	Vitamin D3, omega-3	Baseline cognition and mood

Sleep · hydration · movement

Sleep — 8 hours, non-negotiable. Lights out 22:30. No phone in bed.
Hydration — 2L water minimum. Dehydration tanks IQ by measurable points.
Movement — 30 min walk daily. 2-3x gym or run per week. Movement fixes stress.
Food — protein with every meal. Oats for breakfast on exam days. Nothing heavy pre-exam.
Screens — off by 21:30. Books, not phones, in the last hour.

→ Full nutrition, hydration, sleep, and supplement plan

Exam day routine

06:30 — Wake. Water. Short walk or 10 press-ups to wake the body.
07:00 — Breakfast: oats + protein + fruit. Creatine with oats.
07:45 — Quick 20-min retrieval drill on that day's paper topic (key stats, vocab). Not new content.
T-45 — Caffeine + L-theanine if used.
T-15 — Arrive, toilet, water, breathing (4-7-8 × 4 rounds).
Paper: read ALL questions first. Allocate time. Write.
Post-paper: no post-mortems. Walk. Eat. Decompress. Only look at the NEXT paper's drill, not the last one.
