The youngster was transferred from Pakistan to the UK for life-saving treatment after the bullet grazed her brain.
Surgeons at Queen Elizabeth Hospital in Birmingham operated on her skull and ear. In February, she underwent two successful operations to attach a titanium plate and cochlear implant.
Malala is expected to start lessons at Edgbaston High School for girls in Birmingham later today, the Sun reported.
She has been nominated for the Nobel Peace Prize and a fund has been set up in her name to support girls' education across the globe.
Malala was attacked by the Taliban in October last year after campaigning for girls' rights to education.
A bullet was removed from her head by surgeons in Pakistan, before she was flown to the UK for specialised treatment.
