The Access to Building Services student who studies at the college's Wandsworth Campus, said: "In every situation, there would be something that would test your patience. I wanted to do a good job but sometimes I couldn't do things as quickly as I'd like so I'd get frustrated."
We'll have to tune in to the three-part series to see how well Arsa copes out of his comfort zone, but it's evident he's had the experience of a lifetime.
He added: "I can't give too much away but I can say I absolutely loved the experience. It's changed me by teaching me to be humble, to be happy with what I've got. The people I met didn't have expensive things but they were so happy, really cool and calm. Now I think 'why should I moan when I have more than them?' It's made me a better person to be honest."
You can watch Arsa in action in Slum Survivors on Monday 21 July, 9pm on BBC Three.
