            SA2 2011 practice 2: Q25(secB) what is the shaded part? Ques30, C and D are nets of pyramids not prisms. Ques 5 of section C should round off to whole number.
            Practise paper 7/SA1'11:
            Q4 of section C ???I thought is tessellation...

            SA2 2011 practice 2:Q12(I think the answer should be 3 litres, however I am not too sure...),Q15( It should be of the whole figure, not only the square...),Q17(I think it should be 2240cm2...) and all the questions that Bella mentioned...

            PRACTICE PAPER 7 - CH/SA1'11:Q26(Bk A)(I thought there can be many answers???), Qns 6(Bk B)( You gave us two papers which have the same questions, however for this question, the length of the line they draw for us is different for both papers and when they want us to measure Line PS, the answer will be different...) and the question the Bella mentioned.

            PRACTICE PAPER 7 - NH/SA2'2010:Q28(Bk A)( I think there is a problem) and Q17 of Bk B may have a problem too...

            Thank you.
