OK I know this sounds daft but my Yr 7 son has just greeted me on return from school with "I got a 6B for my Science work today!" Gulp. Is this great, mediochre or a load of old codswallop? I have just realised that if it isn't marks out of 10 or a percentage with a Teacher's comment in red (yes, RED biro)at the bottom then I'm completely ignorant of the current marking system. I can't find any info online but then again I am a complete dinosaur. Can anybody enlighten me out there? Thanks
