Parvati became best friends with Lavender Brown, with whom she shared many interests, such as a love for Divination.
Parvati attended the Yule Ball with Harry Potter in 1994, and a year later she joined Dumbledore's Army, an organisation taught and led by Harry Potter.
She enjoyed the lesson on unicorns, as did the rest of the girls in class.
After the Yule Ball, both Parvati and Padma acted "very cool" towards their dates, Harry and Ron, who had basically ignored them in favour of staring at Cho and Hermione and refused to dance. In her sixth year, Parvati had to convince her parents not to take her and her twin sister out of Hogwarts.
During her seventh year in 1998, she continued her studies at Hogwarts, when it was under the control of Lord Voldemort and the same year Parvati fought at the Battle of Hogwarts against Voldemort and his Death Eaters. Parvati was born to Mr Patil and his wife as one of their twin daughters; the other being Padma.
She was apparently familiar with Pansy Parkinson prior to her enrolment at Hogwarts School of Witchcraft and Wizardry, as during their first year Pansy once made a remark that implied that she had known Parvati for some time.
In her third year, Parvati began taking Divination, which soon became her favourite subject.
She was sorted into Gryffindor at Hogwarts School of Witchcraft and Wizardry, but her sister Padma was sorted into Ravenclaw.Parvati began attending Hogwarts in 1991 and was sorted into Gryffindor house, while her identical twin sister Padma was sorted into Ravenclaw.Parvati shared her dormitory with Hermione Granger, her best friend, Lavender Brown and other two girls.Unlike before when trouble brewed Parvati's parents had not attempted to withdraw her and her sister from school as it had now become compulsory attendance for pure-blood students, which the Patil sisters are likely to be.In May, Harry Potter, Ron Weasley, and Hermione Granger returned to Hogwarts after taking the year off to destroy Horcruxes.
