The subject OMR351 – Mechatronics, with Question Paper Code 81931, conducted on 02-December-2025, there was a printing mistake in the examination. In two questions, the word “Device” was printed instead of the correct word “Design”.

This error altered the intended meaning of the questions. In the context of Mechatronics, the terms “Design” and “Device” refer to different concepts, and the incorrect wording led to confusion for the students during the exam. Since the printed question paper contained the mistake, students were unable to interpret the questions accurately based on the syllabus terminology.

OCH351 – Nano Technology, with Question Paper Code 81823, conducted on 02-December-2025, there was a spelling mistake in the examination. The term “nano material” was incorrectly printed as “non material” in one of the questions.

This spelling error changed the intended meaning of the question. The phrase “nano material” refers to a specific scientific domain within nanotechnology, while “non material” indicates an entirely different and unrelated concept. Because of this printing error, students faced confusion in interpretation during the examination.

CH3302 Mechanics of Solids, with Question Paper Code 80823, conducted on 28-November-2025, there was a printing mistake in the examination. In one of the questions, the value “100” was printed two times, which made the question unclear and confusing for the students attempting it.

Since the numerical values in Mechanics of Solids problems are essential for correct interpretation and calculation, the repetition of “100” changed the clarity and structure of the question. As students were required to rely only on the printed question paper, the mistake resulted in uncertainty in solving the problem accurately.

EE3301 Electromagnetic Fields, with Question Paper Code 81279, conducted on 25-November-2025, there was an equation printing mistake in the examination. Due to the incorrect printed equation, students could not interpret the expression as intended by the question setter.

Since Electromagnetic Field problems rely heavily on correct formulae and equation structures, even a small printing error can alter the meaning and method of solving the problem. This created an unfair difficulty during evaluation as students had to attempt the question without the proper equation provided.

For the subject BM3301 – Sensors and Measurements, with Question Paper Code 80272, conducted on 21-November-2025, one of the questions in the examination was out of syllabus. Since the question did not exist within the prescribed syllabus for the subject, students who attended the exam were unable to prepare for or properly answer that particular question.

Because the syllabus defines the content boundaries for academic preparation, an out-of-syllabus question places candidates at an inherent disadvantage.

The MA3303 examination on “Probability and Complex Functions” conducted on 21-November-2025 Question Paper Code of 81626 contained an ambiguity in Question. The problem statement mentioned the value as “2,3” instead of “2.3”, altering the intended meaning of the question. In mathematical context, 2.3 represents a decimal/mean value, whereas 2,3 signifies two distinct values or ordered pair, leading to confusion among students.

Due to this typographical and conceptual discrepancy, a significant portion of students were unable to interpret the question correctly. Many approached it as a set of values rather than a decimal mean, resulting in incorrect computations and outcomes.
