DC (6) has been getting full marks in spelling tests in recent weeks, but before that wasn't doing so well (think half wrong on average). We haven't been doing much practice at home, about 10 minutes a week.
I hope it's just clicked and/or it's down to the little effort we are making, of course, it just seems a little... unexpected, getting full marks every time all of a sudden.
Is it feasible DC has suddenly improved doing this on their own merit (when we practise at home it's a struggle)? Would a teacher know if a child was cheating? WWYD?
