Ncert book is enough for aiims exam 2017

In 2016 ,
In biology - almost everything was from Ncert (95% questions). But to be on safer side read your coaching class notes also but after Ncert only.
Chemistry - you have to study from coaching class notes along with Ncert.
Physics - coaching class notes / book you prefer (not Ncert). Read ‘points to ponder' given in Ncert at the end of each chapter.
At last but not least take lots of mock tests it will benefit exponentially.
