CEM-STYLE MIXED MOCK 1. This pack is a timed, three-section mock in the multiple-choice style used by CEM (Centre for Evaluation and Monitoring, Durham University) 11+ papers, historically set for a number of UK grammar and independent school entrance tests. CEM papers are known for packing many short, fast-moving questions into tightly sub-timed sections, so pace and moving on quickly matter as much as accuracy. Total time allowed: 50 minutes across three sections, taken strictly in order - once a section's time is up, put your pencil down on that section and move on to the next; do not turn back. SECTION A: NUMERICAL REASONING (18 minutes, Questions 1-20) - fast-paced number, fraction, percentage, ratio, money, time and multi-step word problems. No calculator is allowed. SECTION B: VERBAL REASONING (20 minutes, Questions 21-45) - a cloze passage with 8 missing-word gaps, a comprehension passage with 10 questions, and 7 further verbal reasoning items covering synonyms, antonyms, analogies, odd-one-out, compound words, letter sequences and multiple-meaning words. SECTION C: ENGLISH AND VOCABULARY (12 minutes, Questions 46-60) - 15 questions covering spelling, punctuation, grammar, vocabulary and figurative language. Every question across all three sections is worth 1 mark, with exactly one correct option from A) to E). There is no negative marking, so attempt every question, and use any time left at the end of a section to check your answers before moving on. Total marks available: 60.

The Otter Watch

Original narrative written for Revision Library; no external source reproduced.

Every Thursday after school, Leila cycled the two miles to Foxglove Wildlife Centre, where she had been a volunteer for almost a year. Her favourite task was helping to monitor the otters that had recently returned to the river after decades of absence. The centre's warden, Mrs Ibrahim, had explained that pollution and habitat loss had driven the otters away in the 1970s, but improvements to the water quality had gradually tempted them back.

Leila's job was simple but important: twice a week she walked a short stretch of the riverbank, noting any paw prints, droppings, known as spraints, or half-eaten fish that suggested an otter had passed through. At first she found the work frustrating, since otters are shy, mostly nocturnal creatures that are rarely seen in daylight. Weeks went by without a single clear sign.

Then, one misty October evening, Leila spotted something moving near an old willow root. She froze, barely daring to breathe, as a sleek, dark shape slipped into the water without a splash. It was her first confirmed otter sighting, and she could hardly wait to tell Mrs Ibrahim.

Over the following months, Leila's records became part of a wider survey used by the county wildlife trust to decide where to focus conservation efforts. She began to realise that even small, patient tasks, carried out consistently, could contribute to something much larger than herself. When a local newspaper asked to interview a volunteer for an article on river conservation, Mrs Ibrahim did not hesitate to suggest Leila, whose quiet dedication had, in her words, 'made the invisible otters visible again'.
