Our Offices

Authentic examination papers from Cambridge Assessment English provide perfect practice because they are EXACTLY like the real test. The average duration of each test is 60-minutes (which includes the introductory questions and instructions). Our computer-based admissions tests are taken in exam conditions. Each student completes the assessment independently, working at a computer and guided by on-screen instructions. The organisation and set up of these is done by the school to which you are applying and will vary depending on the school's computer facilities and capacity. A multi-storey facility with no natural overhead light would require far more. Generating enough light could be prohibitively expensive, unless cheap, renewable energy is available, and this appears to be rather a future aspiration than a likelihood for the near future.

Instead, you need to find and read IELTS self-study books with specific instructions on the test process and related strategies, as well as in-depth study materials on vocabulary/grammar for the IELTS test. to have a stable foundation first. Cambridge IELTS Academic 11 Study Guide Includes a comprehensive section of tapescripts and answers, including models and samples for all the Writing tasks, making it suitable for students working partly or entirely on their own. You should spend about 20 minutes on Questions 27-40 which are based on Reading Passage 3 below. Reducing the Effects of Climate ChangeAt the end of the book Cambridge IELTS Academic 11, there is a sample writing section for the questions on the Writing test above. These articles have been evaluated, scored and commented on by the book writers, who are also veteran IELTS examiners.

It took humans 10,000 years to learn how to grow most of the crops we now take for granted. Along the way, we despoiled most of the land we worked, often turning verdant, natural ecozones into semi-arid deserts. Within that same time frame, we evolved into an urban species, in which 60% of the human population now lives vertically in cities. This means that, for the majority, we humans have shelter from the elements, yet we subject our food-bearing plants to the rigours of the great outdoors and can do no more than hope for a good weather year. However, more often than not now, due to a rapidly changing climate, that is not what happens. Massive floods, long droughts, hurricanes and severe monsoons take their toll each year, destroying millions of tons of valuable crops. Those who want to conquer the high-stakes IELTS exam must be familiar with the series of practice questions from Cambridge University Press: Cambridge Practice Test for IELTS. In the article below, 9IELTSwill spend a couple of lines reviewing the second book of this famous series: Cambridge IELTS 11 Academic.The Wheel consists of two sets of opposing axe-shaped arms, attached about 25 metres apart to a fixed central spine. Two diametrically opposed water-filled ‘gondolas’, each with a capacity of 360,000 litres, are fitted between the ends of the arms. These gondolas always weigh the same, whether or not they are carrying boats. This is because, according to Archimedes’ principle of displacement, floating objects displace their own weight in water. So when a boat enters a gondola, the amount of water leaving the gondola weighs exactly the same as the boat. This keeps the Wheel balanced and so, despite its enormous mass, it rotates through 180° in five and a half minutes while using very little power. It takes just 1.5 kilowatt-hours (5.4 MJ) of energy to rotate the Wheel -roughly the same as boiling eight small domestic kettles of water. CEM Select Evaluate provides year-on-year comparability. The results are age standardised and national norms are included.

The US National Center for Atmospheric Research has already suggested that the proposal to inject sulphur into the atmosphere might affect rainfall patterns across the tropics and the Southern Ocean. ‘Geo-engineering plans to inject stratospheric aerosols or to seed clouds would act to cool the planet, and act to increase the extent of sea ice,’ says Rasch. ‘But all the models suggest some impact on the distribution of precipitation.’ Contains a helpful introduction outlining the IELTS format and its scoring, ensuring that students and teachers have a thorough understanding of what is involved in the exam.You should spend about 20 minutes on Questions 14-26 which are based on Reading Passage 2 below. The Falkirk Wheel The concept of indoor farming is not new, since hothouse production of tomatoes and other produce has been in vogue for some time. What is new is the urgent need to scale up this technology to accommodate another three billion people. Many believe an entirely new approach to indoor farming is required, employing cutting-edge technologies. One such proposal is for the ‘Vertical Farm’. The concept is of multi-storey buildings in which food crops are grown in environmentally controlled conditions. Situated in the heart of urban centres, they would drastically reduce the amount of transportation required to bring food to consumers. Vertical farms would need to be efficient, cheap to construct and safe to operate. If successfully implemented, proponents claim, vertical farms offer the promise of urban renewal, sustainable production of a safe and varied food supply (through year-round production of all crops), and the eventual repair of ecosystems that have been sacrificed for horizontal farming.
