In the letter “Privatise the test booking system if you want to improve the service”, which appeared on the letters page 31 in the July issue of BDN, we inadvertently changed a figure crucial to the understanding of the trainer’s frustration at the test booking system. The printed letter stated: “We are regularly faced – at 7am on the ‘opening day’ (10 weeks before the test date, a different day for different test centres) – with an on-screen notice stating: ‘Your trainer booking limit for this test centre is 10’.” It should have stated 0 [zero]. We apologise for the error.
