Another EY application question.

Hey guys, I've been reading posts on here for a while and want to thank you all for advice and tips.

I'm in the middle of applying for EY now, and am having a really hard time coming up for an answer to this question.

'Describe how you have applied something that you have learnt to make a practical difference.'
(150 words max)

are they looking for something I have learnt in uni, or is asking for something I have learnt on a day to day basis?

any ideas or examples at all would be really helpful!
thanks so much!
