Montana State University students are hitting the books hard this week, in preparation for finals.
We stopped by MSU on Monday and found the Student Union Building packed with studiers.
Some say they're already staying up into all hours of the night, fueled by caffeine from coffee and energy drinks.
"Been up all night and studying all morning for this test. It's not fun" said MSU Junior Alex Singleton. His friend Brian Flotkoetter echoed, "finals week is always super stressful."
Others we talked to said they're off to a slow start, before the week starts picking up.
"No real late nights yet," said MSU Junior Logan Boucher.
"I think once we start getting into the evening finals, maybe start pulling the late nights," said Boucher's friend Kilean Lucas.
This is the last week of school for the university, then it's officially summer for all students.
