Do you remember your year 6 SAT's results ?Watch
I know other schools must have been diffrent
No doubt there's a big correlation between these and GCSE and A Lecel grades ...
but I didn't let it define me because I still got mostly A*-B's at GCSE's
EDIT : believe it or not but my cousin got similar to me in year 6 sats and now is in Cambridge studying law, then again our primary wasn't good educational wise
