Nelson has two pet tortoises, one called Wellington and one called Napoleon. Wellington is twice as old as Napoleon. In 10 years, the sum of their ages will be 47. How old is Wellington? A 27 B 18 C 17 D 9 E 11. Think you could answer 50 questions like this in 90 minutes? Every day we think, draw conclusions and make decisions. But how critically do we really think about things? Do we always make logical choices? Do we spot flaws and assumptions in arguments? Do we question what we read or do we let statistics and spin startle us? How do we really think? After a lot of thinking, the team behind "So You Want To Go To Oxbridge? Tell Me About a Banana..." brings you the guide to tackling numerical and verbal reasoning problems effectively and efficiently. Written for students, parents and teachers (and everyone who likes to think), "Think You Can Think?" explores the art of critical thinking and the logic of solving problems. From choosing the cheapest cherries in a supermarket, to scrutinising political debates, this book discusses how to take the most logical approach every time. "Think You Can Think?" is a practical guide to cracking the Thinking Skills Assessment (TSA), an admissions test required for a number of courses at Oxford and Cambridge universities. Packed full of juicy advice and in-depth analysis, this book gives students the opportunity to pit their logical wits against challenging critical thinking questions and complex exercises. The book includes three mock tests that replicate the real thing - each has a separate answer section and an extensive commentary, enabling students to see the different methods of finding answers as well as understanding the theory and logic behind the questions. Written by Minesh Tanna and a team of Oxbridge graduates and edited by Oxbridge Applications, the independent research consultancy that has helped over 50,000 applicants, "Think You Can Think?" equips you with the skills and expertise required for a logical, enquiring mind, both in the heat of the examination room and in everyday life. And as for Nelson's pet tortoises...? You'll find out if you got it right on the inside back cover.
