The Below are the some of the good books for AIIMS. Practice well and do well.

1.      Biology - NCERT, Trueman, MTG Biology. NCERT should be at your Fingertips.

2.      Physics - HCV, DC Pandey for topics which need a liitle bit more work. MTG Physics for you’s question are good for practice

3.      Chemistry - Organic- NCERT, Class notes and I also used Paula BruiceOC as its diagramatic illustrations are very helpful for understanding the major concepts easily and quickly. For questions MS Chouhan’s level 1 and matchmakings. Inorganic - NCERT _all the questions nearly asked_ OP Tondon for reference. Physical - I used Balaji Pub. Prabhat Kumarand questions from Balaji pub. N Avasthi. 

Good luck!
