Hi,
That's a usual written case exercise. I've uploaded some samples here:

The best way to prepare is the following:
- Check if the calculator is allowed. If not - you have to train mental math. I posted the main tips here: https://www.preplounge.com/en/consulting-forum/tips-to-do-big-multiplications-in-my-mind-726#a1422
- Prepare for a regular case interview - it helps a lot. Basically, prep lounge website is about it
- Practice making slides. Look for publically available MBB presentations for reference. Good books are "Pyramid Principle" and "How to make it with charts"
- Practice reading cases fast and prioritizing the information. I found useful two sources:
- Written cases you'll be able to find in google or in case books. I've seen a couple in "Vault Guide to the Case Interview" and "Insead Business Admission Test"
- Harvard cases - either buy or try to find online. You can find a couple of MIT cases here for free: https://mitsloan.mit.edu/LearningEdge/Pages/Case-Studies.aspx Unfortunately free cases don't have the prep questions.
You'll have to create a presentation either on paper or flipboard. The structure can be the following:
Slides 1-2Context, Objective, Recommendations
Slide 2-4: Analysis (Usually 1 slide per analysis / initiative)
Slide 5: Next steps or risks & mitigation
Best
