2015 and 2016 NATA exam was conducted online so there aren't any question papers from 2015 and 2016

in this year mock test provided by coa at tcs website their were no english questions so i guess w'll not find in the main nata paper too.

DQ Edge has all the important chapters in the Mathematics Section . You can refer these for your preparation.

in the actual NATA 2018 exam, as per the mock test link published by coa, the questions will be dipslayed in 2 sections. Math section and aptitude section. you can experience the actual nata test interface here ...

i hope yo uare aware that this year nata will be an online exam !!

The level of questions is not higher than NCERT level as far as I know.

But since it's a multiple choice question pattern exam, it's better to practice MCQ question banks of NCERT level.

for NON - Locals : 150 + in NATA and 95+ in boards

For Locals - 100+ in NATA and 80+ in boards.
