An IT issue meant some students were unable to access their Open University (OU) degree results for several hours.
The Milton Keynes-based institution said its StudentHome system started having problems on Monday evening, but they were resolved by midday.
Creative writing graduate Adam Taylor said it was "frustrating", with it taking 14 hours to get his result.
The OU apologised for the problems, saying: "We know how important results are."
The StudentHome portal is where students access their grades and modules.
The OU said on Twitter on Monday: "We're aware of issues on StudentHome preventing people from accessing their results and are working to resolve this as an urgent priority.
"We know how important results are and apologise for this issue."
