Lulu sorry to hear your news..that's incredibly sad.
DD managed to do some Biology (flash cards) which I did test her on (at DD's request) on Friday. She was in school doing DT project on Monday (5hrs of work), she said she's watched a History video too....and I think that is about it last week apart from two sessions with French tutor (French seems to be going really well I tutor is pleased with DD). She also went through Computer Science revision guide highlighting what she has covered (syllabus not finished yet)
I've taken brave step not to nag/remind DD(she stated she works better if I dont nag/remind). Yesterday she did buy some more flashcards and lined paper organised her Biology flash cards etc. I felt that Dd was seeing lots of the girls from school away on holiday last week so consciously felt that she should not be studying.
School have stated they expect 1-4 hours revision a day ...I think allot of homework is currently revision too. I'm not too concerned about Maths (all the classes in school are currently revision), the French tutor seems to be taking care of French revision in terms of reading ,listening and Oral...DD has all she needs from school (analysed mock papers with marks for each topic/past papers etc), Its just focus and application now 
I'm going to arrange for DD to visit one of her friends who started studying at Pembroke College, Cambridge in September, hoping this may inspire her a little we live reasonably close so DD can get a bus. She'd make a brilliant Maths tutor for DD but I feel it would be unfair to take up any of her time ..
So lovely that the weather is milder !
