On the coaching side we're equally glad to be a part of it!

Best Rote Practice

RocketBlocks (Preplounge has resources too)

Best Practice Strategy

1) Read the Economist (especially the daily graph section) and BCG Insights

2) Ask case partners and/or coaches to focus particularly on your chart-reading skills (i.e. by providing you with cases with many charts) - Bain and Deloitte cases tend to be chart heavy

Graph Interpretation Tips

1) Read the title - and understand it

2) Read the legends - and understand them

3) Remind yourself of the objective / hypothesis in the case, to see where this might fit

4) Find the differences - where does the line graph plummet or spike? Which column is a lot smaller or bigger than the others? Where does change occur? The differences are what matter

5) Talk outloud while interpreting - first, it helps you think and process your thoughts, second, it lets the interviewer provide guidance and course correct if needed.

Hi there!

The way to get better is practicing as much as possible with similar exercises -those targeted at the same skillset-. Hence, I would strongly recommend you practice it with the Integrated Reasoning part of the GMAT exam.

There are free exams in the internet that you can use for practice (the one of LBS MBA page, VERITAS prep, as well as some free trials for courses such as the one of The Economist (gmat.economist)

Furthermore, you can leverage the MBB tests (in myconsultingoffer, psychometricinstitute, and many others)

Hope it helps!

Best,

I agree with both the other experts. There are a couple of points I would add. 
1. Dont be afraid to go back and forth between graphs and see the relationships between them. This is particularly important on Zoom when there might be related graphs. Ask interviewers to flip between the graphs if you want to read something again (Specially found on Bain cases) 
2. Do not forget to the “note” at the bottom. Sometimes this contains key information 
3. If read the first charts where the order of items is x, y, z. Make sure to check the order of the same items on a related chart. I came across it as x, z, y. This triped up my calculation 

Couple of things I want to emphasize 
1. Look for the sudden change/ spike/ drop in the graphs 
2. Do not forget the “So what” at at end
