I've done the RAF tests at Cranwell, trialed the initial BA tests when they switched over to their new format, passed the CTC tests and the Emirates tests of which all have similar versions to the CockpitWeb tests.
The software, near identical to the BA and CTC tests, is a very useful tool.
On your test day not all tests within the CockpitWeb bundle will be given to you as time on the day is limited.
I can't remember which ones were and which ones were not.
