The best years spent in school perhaps are at the primary school level. The Queen Mary's Primary deptt. is an amalgamation of the ancient and the modern where the building is concerned. The original building has had many additions since it was first built. The numbers have increased manifold pressing for more space and more rooms. Additions of rooms have been made for the comfort of the students. But care has been taken not to use the playing space. The open air stage gives an ample opportunity to stage special assemblies and co-curricular activities.
