The Gardiner Block which was built and opened last year (2019) accommodates the collegiate section (A/L classes). The Gardiner Block was donated by Mr Sanjeev Gardiner, grandson of Sir Chittampalam Gardiner – an old Patrician. Thanks to his great generosity. The technology stream of the A/L section functions at the Technology Centre which is adjacent to the Gardiner Block. Presently 426 students are reading in the A/L classes.
