There was a boys’ roof and another for the girls. I remember that the boys did Science while the girls had Domestic Science. Wish I’d have spoken up and asked if I could do Science but girls would never have dreamed of that in those days.I attended Denis Road Secondary Modern when we moved lock, stock and barrel to Sparkhill Commercial early 60's I spent the last couple of years there before leaving school at 15 In 1964. The quirky thing was the playground on the roof.
