Meaning one of the topics would not appear.
A student, who wished to remain anonymous, contacted Somerset Live about the exam and explained that they had been told to revise "at least two topics as a safety buffer". However, he added that a member of university staff made matters more complicated. He said: "Apparently a member of staff gave out a hint in a seminar that the sleep topic was definitely going to come up.
"I did not hear this directly but the people that did only revised sleep, despite lecturers definitely saying to revise two topics." He added: "Before the exam started there was lots of commotion as people made jokes about leaving the exam if the sleep topic wasn't there."
"But these jokes soon turned to tears for a lot of people when the paper was turned over and sleep was not on it." These tears resulted in a 'disturbance' during the exam, with many people choosing to get up and walk out.
Because of this the university has offered students the chance to re-take the paper. The offer was made in an email sent round by Executive Dean, Andy Salmon. In the email, he said: "As you are aware we have investigated a number of complaints about the Advanced Cognitive & Biological Psychology."
"Following this investigation we decided that we would provide students who feel their exam was disrupted, with an extraordinary opt-in opportunity to resit this exam. While the University is not obliged to provide this, we believe it is the equitable thing to do." However not all students were happy with the offer.
