Is NCERT sufficient for AIIMS biology?

Yes, NCERT Biology is sufficient for the AIIMS entrance examination. The following points prove my point further

• Out of 40 MCQs, almost 30- 35 questions are from topics in the NCERT biology textbook.
• The questions related to diagrams in the AIIMS entrance exam are exactly the same as NCERT textbook diagrams.
• Logical reasoning questions are also usually from NCERT textbooks. All you need to do is read your text thoroughly while preparing for the test.

So, it can be safely concluded that NCERT books are more than sufficient for AIIMS. Almost 50–55 questions are from NCERT and with enough revision you will surely ace the exam.
