Seipati Tshabalala tweeted: "I refuse to write my **Final** exams in a tent with dogs patrolling me! I refuse to carry a student card for random spot checks of my identity. Apartheid is supposedly over so I refuse to be subjected to this rubbish in 2017!!"
"I don't know whether to cry or laugh at UCT's idea of writing exams at the rugby fields. Somehow I just believe writing an exam in a tent is not as safe, quiet and calm as the management would claim. Let's wait and see," posted Khangwelo Matodzi.
Protesters have clashed with police on the UCT campus.
Students are demanding zero fee increments for 2018.
President Jacob Zuma on Monday released a report into the feasibility of no fees, but he has yet to make a pronouncement on it.
Cape Peninsula University of Technology spokesman Lauren Kansley said for the past two weeks the campus had been relatively quiet following a tumultuous period of student protests.
"For the entire month of November, we have been incident-free, and we haven't had the need to increase our security."
University of the Western Cape spokesman Luthando Tyhalibongo said the new student representative council had promised a peaceful end to the academic year.
