What began as anger over last month's attack has snowballed into fury over the authorities' response.
Protests reached a peak at the weekend when up to 25,000 marched through Calcutta's streets.
Students say they will not return to class until the vice-chancellor quits.
Dozens of students were injured when Vice-Chancellor Abhijit Chakraborty called in police last Tuesday night to quell a protest on campus.
The classrooms at Jadavpur university are empty. There are students walking about but they are all boycotting their lessons. Some are tattooing the word "shame" on their arms.
The walls are covered with posters, calling on the vice-chancellor to resign. It is the only topic of conversation.
One young student told me "I will not set foot in my classes until he has been thrown out of this institution". A female student said: "if we do not stand up and protest what will happen if someone attacks me"?
Many here are angry and there is a mood of defiance in the air.
Student leaders are meeting to decide what to do next. Whatever decision they take it will be some time before classrooms here are full of students again.
The students accused the authorities of brutality, saying they were attacked while they were protesting "peacefully".
Mr Chakraborty has defended the police action. He said he called the police and asked them to rescue him and some staff members after they were surrounded by the protesting students for 10 to 12 hours.
On Sunday night the West Bengal government said representatives of its education department would form a panel to investigate the assault.
The student was attacked on campus on 28 August. A police case was registered, but no arrests have been made yet.
The students have been protesting against police inaction since 11 September and have accused the university authorities of apathy.

The two male suspects are believed to have scaled a fence in the back garden and broken into the house in Ashbourne Road, Mitcham, sometime between Saturday morning and Monday afternoon when the theft was discovered.
The thieves damaged cuddly toys, puzzles and games belonging to the victim's' baby and stole gifts including jewellery, photographic equipment, a tablet and a laptop computer.

The cuts affected power stations and public transport, including Istanbul's tram and metro systems.
A crisis centre has been set up at the energy ministry.
Prime Minister Ahmet Davutoglu has said all possible causes are being examined, including terrorism. The cut hit at 10:36 (07:36 GMT) on Tuesday morning.
Power cuts were reported in at least 40 of Turkey's 81 provinces.
Traffic lights stopped working in several parts of Istanbul and Ankara during the outage, causing traffic jams, while rescue teams were called to help people trapped in lifts or stuck underground at metro stations.
By Tuesday afternoon, electricity returned to parts of Istanbul. Energy Minister Taner Yildiz said about "80% of Istanbul's electricity has been restored" and he expected power to return to the rest of the country soon.
Istanbul's transport company said all of its routes were back up and running.
Turkish TV also reported that power had been re-established in the cities of Edirne, Tekirdag, Erzurum and Trabzon.
"Our main target right now is to restore the network. This is not an incident that we see frequently," Mr Yildiz told Turkish media.
Turkey suffers from sporadic electricity cuts but locals say they cannot remember such a nationwide cut for a generation, reports the BBC's Mark Lowen in Istanbul.
One of the few cities unaffected by the power cut was Van in the east of the country, where electricity is supplied from Iran.
Students at Calcutta's Jadavpur University say they will continue a boycott despite a government vow to set up a panel to investigate a sexual assault on a female student.
