During an examination being taken by 30 first-year Electrical and Electronic Engineering students, the first page of the answer scheme was included alongside the question paper due to a printing error.
The Department became aware of the situation within five minutes of the exam beginning. The exam was halted and the papers were removed from the students.
The Department reviewed the situation carefully and concluded that students would not have been able to use the information to any advantage during the short time they had access to part of the answer scheme.
The exam questions required students to demonstrate the application of an algorithm to a given data set setting out detailed reasoning in their solutions. The required algorithms were not revealed in the answer scheme.
Once this was established, the exam recommenced with the correct version of the question paper.
One of the students, speaking to newspaper The Tab, said:
"I raised my hand briefly, hoping to inform the invigilators of the error, but quickly retracted it after realising I might be the only one with the mark scheme."
On looking around, I heard one of my peers sniggering at the front of the exam hall, and then seconds later the whole hall was in stitches as our examiners looked on blankly. Surely the best start to any of my exams."
A red-faced convenor decided to remove the mark schemes from the test and give it back to students, hoping that they would not be able to remember most of the answers.
London Metropolitan University may become the first in Britain to be banned from educating foreign students, according to reports.
The University has previously been allowed to sponsor visas, but authorities no longer trust it to monitor its students and ensure they don't become illegal immigrants.
It means that around 2,600 students from outside the European Union will have 60 days to find places on other courses at a different institution, or they will be asked to leave the country.
However a Boarder Agency spokesperson said: "We have not made a decision yet.”
They added: "Any education provider has to meet strict standards, ensuring they provide high quality education, and take their immigration responsibilities seriously. We will not tolerate any abuse of the immigration system.”
