Hi Sergey,
The usual steps to follow in a written case are:
1. Learn how to define a plan of action and stick to that
2. Practice graph interpretation
3. Work on quick reading and quick understanding of key information
4. Practice quick math
5. Learn how to communicate your slides/answers (if required)
At the following link you can find a detailed description of each of these areas:

When you have also to prepare slides, quoting a previous answer I would also recommend to work on
#1: structure the order of the slides
Normally the structure for a 5-slide presentation is the following:
- First slide sums up the question and provides the answer
- Second, third and fourth slide have the supporting arguments for the first slide
- Fifth slide has the next steps
#2: structure the content of each slide
There are three basic components for slides:
- Title
- Chart or data
- Label for chart
Many people structure the title as the mere description of what the chart is telling. A great title, instead tells the implication of the graph. Eg say the graph is showing a cost structure for a division. A bad title would be: Cost structure from 2005 to 2015. A good title would be: Cost structure of Division XYZ is not sustainable”. A great title would be Cost structure of Division XYZ is not sustainable due to ABC, assuming you have insides on the cause. The rule of thumb for the title is that if you read all the titles of the slides together you should get a clear idea of what is going on.
# 3: present the slides
When you present, I would suggest the following steps for each slide:
- Introduce the slide: “Let’s move to slide 2, which will show us why we have an issue with this division”
- Present the main message of the slide: “As you can see, we have a cost structure which makes for us not feasible to be competitive in this market”
- Provide details: “The graph, indeed, shows how our fix cost is XYZ, while competitors can benefit from economies of scale. Indeed…”
To answer your second question: you will have to use the information in the package to create slides, of course adding your own insides.
Hope this helps,
Francesco
Thank you so much!
