Morgan Stanley IBD Assessment Centre - individual case study advice?

Hello! I'm a non-finance major who has made it to the final round in the Morgan Stanley SA interview process.

I've been invited to an assessment centre and my main concern here is with the individual case study. I know this material might be hard to come by, but I was wondering if anyone could provide any insight into what exactly my individual presentation should entail - will I need to crunch numbers? Produce graphs? Run DCF analyses? What would constitute a good analysis / presentation for the individual case study?

Any insight appreciated!
