Dear aspirant,

My expertise isn't in NATA so i'll suggest jee

For organic chem- O.P.TONDON 2000 pages book, contains everything you would need to clear organic chem with detailed examples and 4level of problems 

For inorganic chem choose Cengage 

for maths also i will suggest you to pick cengage as many engineering students  refer their books for Initial semister exams

for physics if you want to have strong base i suggest haliday and resnick

mcq point of biew DC PANDEY 6 volumes

Maths-sk goyal for co ordinate geometry

integral calculus- amit agarwal

or you could choose all the volumes of cengage, they will be difficult but have variety of sums and detailed explaination.

Please notes these are for jee mains althogh cetrian books like cengage can extend to jee advance dc pandey won't.
