MHT CET Question Paper 9 May 2023 (Available): Shift 1, 2 Memory-based Questions with Answer Key Solutions PDF

MHT CET Question Paper 9 May 2023 Shift 1: The first shift of the first day of MHT CET 2023 concluded today on, May 9, 2023, from 9 AM to 12 PM for the PCM stream. The overall difficulty level of the question paper was Moderate. The maths section in the MHT CET Question Paper 9 May 2023 Shift 1 received mixed reactions between moderate to difficult. The physics section was moderate while the chemistry was easy compared to the other two subjects. The mode of the exam is a computer-based test which means students will not have access to the question paper, and the students of the upcoming shifts will not be able to access the previous shift's question paper copy for an additional and important step in their practice. However, such students can obtain the memory-based MHT CET 2023 question paper with answers for the 9 May Shift 1 exam here. As the following questions are memory-based, all 150 questions in the exam will not be covered, and only those questions received from test takers of the May 9 Shift 1 exam shall be added here.
