A. ½ mark each = 3 marks
B. 1 mark each = 4 marks
C. 1 mark each = 3 marks
D. ½ mark each = 3marks
E. ½ mark each = 9 marks
F. 2marks each = 8 marks
G. ½ mark each = 4 marks
H. 1 mark each = 5 marks
I. 1 mark each = 4 marks
J. 1 mark each = 4 marks
1/3 mark x 12 = 4 marks
K. ½ mark each = 3 marks
L. 1 mark each = 2 marks
M. 2 marks each = 4 marks
N. 1 mark each = 3 marks + 1 mark = 4 marks
O. 1 mark for working + 1 mark for answer = 2 marks
1 mark for working + 1 mark for answer = 2marks
1 mark for working + 1 mark for answer = 2 marks
P. 1 mark for working + 1 mark for answer = 2 marks
1 mark for working + 1 mark for answer = 2marks
1 mark for working + 1 mark for answer = 2 marks
1 mark each = 2 marks (1/2 mark for working each)
1 mark each = 2 marks
