MEI Conference July 2008 Discussion on C1 and C2 Some issues arising from C1 exams • no calculator in C1 o errors in basic arithmetic eg fractions, negative numbers, 7 × 6 ≠ 42 o difficulty in squaring eg long methods for 2.52 or 2.52 = 4.25 seen instead of (5/2)2 = 25/4 = 6.25 • use of time • sketch graphs o often done on graph paper (not on list of materials now, but some centres still issue) o difference between sketching and drawing often not appreciated • basic algebra o lack of facility in basic manipulation / lack of confidence from weak candidates eg problems with factorising o elegance of solutions from many strong candidates • use of C2 topics • when to enter o Jan yr 12 or June yr 12? Pros and cons of Jan entry for weak candidates o retakes Jan/June yr 13 Some issues arising from C2 exams • use of long methods, especially in trigonometry o degrees not radians • logarithms and the linear law • indices o lack of facility affecting differentiation and integration • not showing sufficient detail of method • calculator errors such as premature rounding; mode for trigonometry • lack of mathematical maturity Resources available Specification Past papers Examiners’ reports C1/C2 textbook C1 revision guide C1 and C2 ask the examiner jm MEI conf/ july 08 MEI practice papers MEI Module summary sheets MEI Examination question analysis sheets Personal Tutor CD
