My mother has just found my old school reports.
The Primary School ones are fine, but the Secondary School ones are far from glowing - various "could do much better", "doesn't work hard enough" type comments for virtually everything 
However, I did come out with a string of very good O and A levels.
DD just had her first Y7 report and it was cringeingly fantastic DS's reports are less glowing, but still OK.
Have times changed - are teachers just more positive now?
And would it be a bad idea for them to read mine (and DH's similar!) knowing that we did well academically despite doing as little work as possible!
