According to Norway's Dagbladet newspaper, Breivik applied again to study politics earlier this year, and expects to hear back from the university on July 20th.
Since starting his 21-year sentence in 2012, the 36-year-old killer has continually sought to study politics, applying to study at the University of Oslo for the first time in 2013.
The first time he applied, he was rejected due to his lack of a high school diploma. He then completed his diploma, but in 2014 still had insufficiently high grades to win admission to the university.
Now, after he retook a series of exams last year, his lawyer Øystein Storrvik expects him to be permitted to study.
"His grades are quite good," Storrvik told The Local. "It's not so easy to get accepted to study this subject."
Dag Harald Claes, the head of the university's politics department, told Dagbladet that if Breivik is permitted to study, he will not be able to pursue a full degree, as five out of the nine modules in the course require students to take part in seminars and face-to-face meetings, something Breivik is not permitted to do under his prison regime.
In 2013, Breivik was admitted to study a single preparatory politics module, intended for those planning to take a degree at the University, with course and lecture materials sent to a study room reserved for him in Skien prison in Telemark, south of Oslo.
Breivik dropped out of the prestigious Oslo Commerce School months before graduating in 1998, an early setback to which, during his 2012 trial, several friends attributed his mounting sense of failure and retreat into fantasy.
Breivik killed 77 people in his 2011 twin attacks on an Oslo government tower block and a Labour Party youth camp on the island of Utøya.
