I specifically mention "English". I'm a non-native English speaker, What I feel uncomfortable is I can't get the gist of some 600-700 level and all 700-800 level questions in both quants and verbal section.
I know I'm unveiling GMAT question structure but I'm just looking for some help.
Please let me know, If there are any materials or books which teach more about English usage in GMAT quant/verbal section or the infrastructure of language in GMAT questions. So I could read and get custom to it.
To add : How to develop reading-between-the-lines skill :)
