Ninety days out from your ICAN diet, most candidates do one of two things: they panic and buy every textbook in sight, or they convince themselves they'll "start tomorrow". Both approaches end the same way — in an exam hall feeling under-prepared.
The good news is that ICAN is a predictable exam, and predictable exams can be beaten with a predictable process. This article walks you through a 90-day plan built on three phases: map, learn, and simulate. It assumes you are sitting the current diet — always confirm the syllabus year on the ICAN portal before you print anything — and that you study with a toolset that gives you immediate feedback, because the single strongest predictor of exam performance is how many questions you have answered under feedback before exam day. You cannot revise for an objective-paper exam by reading alone.
Phase 1 — Days 1 to 14: Map the terrain
The fastest way to waste 90 days is to start studying without a map. For the first two weeks, resist the urge to read chapters in order. Instead:
- Print the syllabus for every subject you're sitting. Note the paper weightings. A subject worth 60% of a paper deserves more of your week than one worth 15% — study effort should follow marks, not enthusiasm.
- Take a diagnostic test. Ten to fifteen questions per core subject is enough. The point is not the score; it is the pattern. Did you run out of time? Did you miss facts you actually knew? Were the misses spread across every topic or concentrated in one?
- Settle exemptions early. If you hold a prior qualification that frees you from a subject, sort it out before you start studying, not after. Studying a subject you're exempt from is the most expensive waste of a week in the entire diet.
- Set a weekly hour target per subject, and write it down. Plans you can't state in one sentence are plans you won't follow.
By the end of two weeks you should be able to say three things precisely: these are my strong subjects, these are my weak ones, and here is the exact list of topics I must master first.
Phase 2 — Days 15 to 56: Learn in short loops
The middle six weeks are where the result is made. The classic mistake here is studying a topic for an hour and moving on — it feels productive, but it produces almost no retrieval strength. Replace it with a short loop you repeat for every topic:
- Learn one topic — read the lesson, watch the breakdown, follow the worked examples. Keep this to 30–45 minutes.
- Answer 10–15 questions on that topic immediately, before you look at your notes again.
- Grade yourself instantly and read the explanation for every single miss, including the ones you "knew".
- Log each error as one of three types: a conceptual gap, a careless slip, or a time-pressure mistake. The label matters — each one needs a different fix.
- Review yesterday's misses tomorrow via flashcards before you start anything new.
Why this loop works: answering questions immediately after learning forces retrieval, which is what the exam actually tests. Re-reading a chapter feels easier and therefore convinces you you've learned it; retrieving an answer from memory is hard, and that difficulty is exactly what makes the memory stick.
A steady weekly rhythm keeps the loop sustainable:
| Day | Focus |
|---|---|
| Monday | New topic + topic quiz + flashcards |
| Tuesday | New topic + topic quiz + flashcards |
| Wednesday | Re-quiz last week's weak topics only |
| Thursday | New topic + topic quiz + flashcards |
| Friday | New topic + topic quiz + flashcards |
| Saturday | Timed full-subject practice set |
| Sunday | Rest, or a light pass over your error log |
Keep sessions to 90 minutes at most — 45 minutes of focused work, a real break, then 45 more. Ten good hours a week beats thirty zombie hours every time.
Phase 3 — Days 57 to 90: Simulate and close gaps
This is the phase most candidates skip, and it is the one that decides pass or fail. In the final month:
- Sit one full-length timed mock per week, under exam conditions — no phone, no notes, no pausing, and a timer you actually respect. A mock you pause is a mock you're lying to.
- After every mock, classify each miss. Time-pressure errors mean you need more question reps, not more reading. Careless errors mean you need a slower, checking habit. Conceptual gaps mean you need to go back to the lesson. Three different diagnoses, three different fixes.
- Close gaps in the right order. The three weeks before the diet belong to the topics that keep appearing in your error log — not to the topics you enjoy. Comfort is the enemy of preparation.
- Taper in the final week. Stop trying to learn new material. Review summaries, re-sit a light practice set, and sleep. Cramming in the last 48 hours mostly manufactures anxiety.
The three traps
- Skipping the diagnostic — you can't fix weaknesses you haven't named.
- Reading instead of doing — for an objective-paper exam, questions are the curriculum.
- Sitting your first mock too late — your first timed mock should happen before you feel ready, not after. It's diagnostic, not a verdict.
Where ilymi fits
If you want this exact plan without assembling the toolkit yourself, this is what ilymi was built for. The study library walks each ICAN level through subjects, topics and lessons in syllabus order, with tables, diagrams and embedded video — so you are never studying out of sequence. Every lesson drops you straight into topic quizzes with instant explanations on every miss, and a spaced-repetition flashcard deck automatically feeds you the cards you keep getting wrong. When you reach Phase 3, the CBT simulator lets you sit full-length timed mocks that mirror the real exam interface, so exam day feels like a rerun. Start with the free diagnostic — because a 90-day plan is only as good as the map it begins with.
