I’ve reported this thread, because of all the repeated spamming.
The hints on remembering tables are always useful, but the only way of doing better in random question tests is to practise random questions.
We had a book full of strips of questions, starting with a mix of one table, then moving on to a mix of different tables. The aim was for the child to improve on its own score, not to be compared with others.
Lots of apps test random tables too-Table Mountain for example, but the app needs to
focus on the answers, not the game.
