Physics - Units and Dimensions

Practise 16 BITSAT previous year questions on Units and Dimensions, compiled from papers spanning 2009 to 2024. Each question is pulled directly from the actual exam paper it appeared in, so you're practising in the exact style and difficulty BITSAT tests.

Units and Dimensions has been asked in 13 of the 16 years of BITSAT papers analysed (2009–2024), with 16 questions in all. 50% of them were easy, 50% moderate and 0% tough. Most of its questions came from 2023, with 3 questions that year. In the last three years (2022–2024) it had 5 questions across 4 papers, about 1.3 per paper.

The chapter's 2 topics are not weighted equally: Dimensions (13 questions, 81%) and Units (3 questions, 19%) have been asked the most. Dimensions has also led over the last five years, with 4 questions.
