Our son is in his last year and due to having a bad dose of the flu last month he had to ask for extensions for 2 assignments which he was given. He submitted one but wanted another day past the extension to complete it and was told that was fine. He was then told a few hours later that due to the university firewall he wouldn’t be able to submit his assignment later and he emailed his tutor about it. He has now been told that he needs to do the assignment all over again in August in something called a ‘first sit’ which means he won’t be able to graduate in July with his friends. This seems unreasonable in our opinion especially as he has never asked for extensions before or failed anything etc. Any ideas on how to deal with this?
