Zoology - Digestion and Absorption

Practise 33 AIIMS previous year questions on Digestion and Absorption, 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.

Digestion and Absorption has been asked in 12 of the 19 years of AIIMS papers analysed (2001–2019), with 33 questions in all. 30% of them were easy, 27% moderate and 42% tough. Most of its questions came from 2019, with 5 questions that year. In the last three years (2017–2019) it had 11 questions across 5 papers, about 2.2 per paper.

The chapter's 12 topics are not weighted equally: Vitamin (8 questions, 24%), Stomach (7 questions, 21%), and Intestine (4 questions, 12%) have been asked the most. Stomach has produced the most tough questions (3).
