There will be more test centres, I think at least 8, with a better geographic spread across the country especially in the midlands and north.
The current schedule for 2104 will still be exams in the first week of the month, but after this expires in December times will be more flexible.
Good news is that results will be available much more quickly, at the end of the day or the end of a sitting. No more waiting around for weeks.
There will also be feedback on where you slipped up, so long as the result is better than 50%.
Overall seems a very good move forward.
