Swords are working on a 5-6 week wait time.
My brother applied in November and said he wasn't available to do it from Dec - Mar due to studying for his leaving.
As soon as the 3 months were up he was contacted and told that Raheny was still back logged but if he was willing to switch to a new test centre he could sit it in Ballymun or Swords 2 weeks later. He took the appointment in Swords, failed and reapplied that same day. He was called again in May, given a new date and passed on May 19th.
He done it twice in a matter of month's so I'd say that it depends on the test centre. He would probably still be on the waiting list for Raheny if he chose to wait.
