Oddsocks - Do you think your DD is feeling peer pressure?
DD back home with me today and she's done some revision whilst away 
DD did one of the specimen computer science papers today and timing looks to be very tight on the second paper (she was also struggling to squeeze the programming data into the answer fields)...she didn't answer some questions which we have gone through together (some she knew the answer to but didn't realise because of the wording of the question and couple related to topics not yet covered) ...CS is the only subject where they have not finished the syllabus (the mock was lacking in content according to DD). Just surprised the teacher would not take 1 day out of 3 weeks Easter holiday to go in like most of the other teachers have done.
DD going to do paper one tomorrow and see how that goes ...very worthwhile doing the specimen paper at this stage.
I ordered the Corbett Maths Flashcards for her and she's happy with those too.
