Zoology - Chemical Coordination and Integration

Practise 36 AIIMS previous year questions on Chemical Coordination and Integration, compiled from papers spanning 2001 to 2019. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty AIIMS tests.

Chemical Coordination and Integration has been asked in 16 of the 19 years of AIIMS papers analysed (2001–2019), with 36 questions in all. 39% of them were easy, 33% moderate and 28% tough. Most of its questions came from 2018, with 5 questions that year. In the last three years (2017–2019) it had 10 questions across 5 papers, about 2 per paper.

The chapter's 9 topics are not weighted equally: Pituitary Gland (8 questions, 22%), Pancreas (8 questions, 22%), and Adrenal Gland (7 questions, 19%) have been asked the most. Pancreas has produced the most tough questions (3).
