Mental Arithmetic

[NickM]

Ages ago I remember some kind person wrote a thread with a URL to a site which had various mental arithmetic questions. Thought this would be helpful for my second stage interview with NATS next week.
Looked through the search and can find chuff all. Does anyone know what it is??????

The second stage of the ATC testing doesn't really look at mental arithmetic, except some simple basic sums as part of one of the computer tests (I sat them in late 2000 and no-one coming to the colege since has mentioned any changes). During those you have to demonstrate multi-tasking - responding to stimulus on the screen with one hand, answering mental arithmetic questions on a different part of the screen with the other hand.
