High-Frequency Exam Vocabulary

Welcome to your CEM 11+ Vocabulary & Spelling course! In this first lesson, you will learn the words that appear most often in CEM-style exams. Unlike GL tests, the CEM exam does not follow a fixed format — the types of questions can change from year to year. However, one thing stays the same: vocabulary is tested heavily, and knowing these high-frequency words will give you a real advantage.

Why Does Vocabulary Matter So Much in the CEM Exam?

The CEM (Centre for Evaluation and Monitoring) exam, used by many grammar schools across England, places great importance on your word knowledge. Vocabulary questions can appear in several forms:

Synonym and antonym matching — choosing a word closest or opposite in meaning
Cloze passages — filling in missing words from a passage
Odd-one-out questions — finding the word that does not belong in a group
Words in context — working out meaning from a sentence

Because CEM questions are designed to be unpredictable, having a wide and deep vocabulary is your best preparation.

How to Learn These Words Effectively

Read the word and its definition — make sure you understand it.
Say the word out loud — this helps your memory.
Write your own sentence using the word.
Test yourself — cover the definition column and see how many you can recall.
Use the word in everyday conversation — this is the best way to make it stick.

Top Tip: In CEM exams, you often need to understand a word in context, not just know its dictionary definition. Always practise reading sentences and working out meaning from the clues around the word.
