Love his honesty. I am faintly curious to see if ds2 will pick up his pencil at all to do his. It is apparently human nature to stop when the goal is reached (Horizon, Monday night) but most are not as aware of doing so as your son.
Ds is exactly the same Polter, if he gets even one question wrong or feels he hasn't done enough, this amounts to him being 'stupid' and 'rubbish'
He came home the other day and told me the teacher had said he was 'stupid'. I thought this very unlikely, when I asked him some questions, it amounted to ds thinking he had not done enough work and ds thinking that the teacher would regard this as him being 'stupid'.
I never did my mocks. The clue was in the name. What is the point of spending all that energy on something that didn't count? Besides, I hadn't even read the text book by that stage, let alone started any revision.
I'd fret and do an intervention if this was his approach to his GCSE's, but you have years to change his thinking in time for those. In the meantime let him just get thru SATs in the way that means minimal anxiety for him, as at this age emotional stability and security should be the priority.
