Scheme of Work for Year 8 2012-2013 There are 4 Levels tests plus 1 Summer Exam. There should be enough spare lesson time, to go over tests and exams and still complete the syllabus. If your class struggles for some reason to understand a lesson, do not feel you have to continue to the next lesson regardless. Emphasis on the use of using their calculators efficiently at all times and using estimating to check they have sensible answers.
