what do you count as 'study', reading? jigsaws? playing word games? doing puzzles together? or just practice papers
Difficult one... if playing games like missing object or reflections, that you would not do if you were not taking the 11+, then that is studying.
Reading is not studying unless you are only doing so as you are taking the 11+ or are forced to read, when one usually would not.
Studying is learning, reading maths, NVR, VR books, videos etc, doing papers, or general questions and activities directed towards studying eg spartial reasoning games.
It is funny how there are so many formal 11+ courses and tuition centres, and all these people will "study" for more than 4 hours a week.
Even before Easter holidays my child's school were giving children more than 1 hour a night homework and in total over 10 hours a week SATS revision. (So many parents complained their children did too much). Wait for seconary school!
