I cannot authoritatively say its an issue, but a guy was turned back because of a conditional offer on the 17th july. He had to bring his CAS showing that he had paid 10,000GBP. That was still turned down because it didn't have the school's logo on it,so the board believed it was forged. His mistake was that the offer letter he presented was the initial conditional offer he was sent. A third party helped him secure the admission so it wasn't possible for him to just go to the business centre downstairs and print the unconditional one from his email since all correspondence with the school was done by a third party. Those who were interviewed after 7pm on the 17th witnessed this. It could just be a one-off situation because there were other people who were not asked about NYSC discharge certificate. Its different strokes for different folks.
