Minor curiosity point.... Does anyone know why engg has two g's here?

I'm sure it mean engineering but i've never seen that abbreviation, he motioned he's from India, is that where this comes from or is it just an individual quirk?

Yes in India we abbreviate as Engg. I never noticed till now that perhaps other countries don't :-)
