How accurate are the NC level given as results of the Education City quizes??
DS just did a numeracy one unaided and came out a 2B. Was told at parents evening 2 weeks ago he came up a 1A and she had just assessed him as a 2C.
I then went through it with him - didn't give answers but got him to think about the question and he got 2A 
Obviously no prompting in his SATS tho which I am aware of.
Thanks for replying.
