Hi, please advice which GMAT prep company is the best to help with Data Insights preparation.
Prep companies won’t be able to help you a lot with data insights tbh.
It does not involve any concept as such. DI just needs very careful reading and comprehension skills which a coaching can’t help much with.
Practise as many official questions as you can while taking due care to read each word carefully and understand what the question is presenting you with and what it’s asking.
The prep companies will just teach you things like different kinds of graphs and correlations and stuff. But that’s pretty basic stuff which you probably already know
Data sufficiency(which is a part of DI now) is something you would have already learnt in the quant section prep
