Nicola Sturgeon has urged students to abide by new lockdown measures introduced by universities.
The measures were agreed by institutions on Thursday as part of efforts to stem a number of outbreaks on campuses across Scotland.
They include a ban on visiting pubs and restaurants as well as potential to be removed from studies if found to be putting others at risk.
The Scottish First Minister tweeted: "To all students - I'm so sorry COVID is making this special time of your lives so tough.
"But it won't be forever and the more we get the virus back under control now, the sooner you'll get a bit of normality back. So, please do what's being asked of you."
It comes after students across Scotland were told not to go to pubs and those who repeatedly flout coronavirus guidelines could be thrown out of university, under new rules.
Representatives from higher education in Scotland met to discuss a range of measures which would be introduced amid concerns over a number of outbreaks since term started.
It has seen students required to download the Protect Scotland tracing app and have been asked not to attend bars at the weekend.
Universities have also now agreed to introduce a "yellow card, red card" system to breaches of student discipline that put students and others at risk, which could result in an end to studies.
Gerry McCormac, convener of Universities Scotland, said: "University leaders share the Scottish Government's complete commitment to keeping the student population and the wider community safe.
"We have already implemented strict measures to ensure the safety of the university environment, both for teaching and for student residences.
"We have seen the majority of students live up to our expectations of responsible behaviour, but a minority have not.
"Everyone across the nation shares the concern at seeing students in residences test positive for the virus and we will act decisively to deal with this.
"The additional actions we will take to drive down the transmission of the virus in student accommodation build on the wide-ranging measures already agreed with Scottish Government.
"Taken together, we are confident that these will help significantly to control the virus in student accommodation and impact on the number of positive cases; after the inevitable time-lag caused by some existing cases not yet being symptomatic.
"Our top priority is making sure that students that have tested positive and those quarantining are well-supported and ready to return to their studies.
"We appreciate this isn't what students would have expected from their first few weeks at university, but it is critical that they play their part in suppressing the virus."
