BCS601 Software Engineering Important Questions 2026 (AKTU)

Repeat analysis + most-asked questions, unit-wise

What we did: built from all 4 AKTU Software Engineering papers (2021-22–2024-25): 96 questions grouped into 53 distinct questions, 24 of which were asked in more than one paper.

How much of the paper repeats?

  • Repeats are real: when we checked each newer BCS601 paper against the papers before it, on average 69% of its marks were questions already asked in an earlier paper.
  • 2023-24 paper: 54% of marks were repeats (8 of 14 repeated questions were in our top list).
  • 2024-25 paper: 84% of marks were repeats (13 of 19 repeated questions were in our top list).
  • Topic weightage is a guide, not a guarantee: our Tier 1 + Tier 2 topics covered 61% of the next paper's marks — picking the same number of topics at random would have covered about 56%.

Across 10 subjects and 23 papers we tested, 43% of marks repeated earlier questions on average.

FAQ

Which units of BCS601 carry the most marks?

Unit 1 (Introduction, 24% of past marks) and Unit 3 (Software Design · Software Measurement and Metrics, 23% of past marks).

Do AKTU Software Engineering questions repeat?

Yes. On average 69% of the marks in each newer BCS601 paper came from questions already asked in an earlier paper, and 24 questions have appeared in more than one paper.

How is this list made?

Every question from the 4 papers (2021-22–2024-25) was mapped to the current AKTU syllabus and grouped with the same question from other years. Questions are ranked by how many papers they appeared in, then by how recently.
