“Seems to be loads of 'bickering' amongst him and his friends which is unheard of - I suspect that the pressure is getting to them all and things will calm down once the exams are over.
Has anyone else experienced this?”
Oh yes, it certainly happened in DD’s friendship group.
NewModelArmyMayhem18 DD took geography last year. It was the first year of the new spec and both the teachers and students struggled with it. There seemed to be insufficient guidelines for the teachers regarding the coursework, and they weren’t allowed to advise the students in any way. Fortunately DD got a good mark for her coursework (which she sweated blood sweat and tears for). I think she ended up submitting around 6,000 words.
“A teacher friend told me that the mocks can be a kick up the backside when needed Piggy”
They certainly can. DD was predicted an A and got a D in one of her mock papers in the Easter mocks. She had done loads of revision, but just didn’t understand the questions. She did eventually achieve an A in the real thing, but she did need that kick.
