I thought it might be useful to have a separate thread on here listing games/tools/websites where people can go to help hone their reactions, mental arithmetic, and other general ninja skills required to do well in the computer tests that make up Stage 2 of the NATS application process for trainee ATCOs.
Now I know there may be no directly relevant games out there, but there will be plenty that might be helpful, and trawling through 300 pages of the big thread can be arduous at the best of times.
So - any suggestions? Extra points go to people who suggest websites that aren't blocked by my company's firewall
