How to Prepare for CEM (The Right Way)
Since CEM is designed to be tutor-proof, focus on building genuine ability:
1. Build Deep Vocabulary
Vocabulary is the single most important factor in CEM success:
- Read widely and often (novels, non-fiction, newspapers)
- Learn word roots, prefixes, and suffixes
- Play word games (Scrabble, crosswords)
- Aim for 20,000+ words by Year 6
2. Develop Processing Speed
CEM's rapid pace rewards quick thinking:
- Daily mental maths drills
- Timed reading exercises
- Quick puzzles and brain teasers
3. Wide Reading Programme
Reading is the foundation of CEM preparation:
Year 4-5: Classic children's literature, age-appropriate non-fiction, The Week Junior
Year 5-6: More challenging fiction, adult non-fiction, broadsheet articles
Preparation Timeline
| Time | Focus |
|---|---|
| Year 4 | Daily reading habit, vocabulary building |
| Year 5 | Increase reading complexity, general reasoning |
| Year 5 Summer | Intensive reading, timed practice |
| Year 6 September | Light revision, wellbeing, confidence |
What Makes CEM Challenging
- Speed Requirements - Very little time per question
- Vocabulary Demands - Words often exceed Year 6 expectations
- Mental Switching - Rapid transitions between subjects
- Unpredictability - Can't rely on familiarity
Common Mistakes to Avoid
Preparation Mistakes
- Buying unofficial "CEM Practice Papers" (don't reflect real exam)
- Neglecting reading (no drilling replaces genuine vocabulary)
- Over-tutoring (creates anxiety without building ability)
Exam Day Mistakes
- Spending too long on questions
- Panicking at unfamiliar questions (CEM expects this)
- Poor pacing
