Thomas was an excellent tutor, understanding and patient. Only minor criticism was that I would have liked to cover more mock exams which were dedicated to the 2391-50. That may come when you get more candidates doing the 2391-50 rather than the 2391-52. However I certainly didn’t feel under prepared for the exam and it was good to get a ‘refresher’ on the the periodic testing side which I already hold my qualification for. Also, really appreciate your understanding in postponing my practical exam to a more convenient date as it was my error in booking the original date without running it past the senior staff at work.
