How much of the paper repeats?
- Repeats are real: when we checked each newer BEE403 paper against the papers before it, on average 58% of its marks were questions already asked in an earlier paper.
- 2024-25 paper: 67% of marks were repeats (8 of 14 repeated questions were in our top list).
- 2025-26 paper: 50% of marks were repeats (9 of 11 repeated questions were in our top list).
- Topic weightage is a guide, not a guarantee: our Tier 1 + Tier 2 topics covered 57% of the next paper's marks — picking the same number of topics at random would have covered about 52%.
Across 10 subjects and 23 papers we tested, 43% of marks repeated earlier questions on average.

FAQ
Which units of BEE403 carry the most marks?
Unit 3 (Transient Circuit Analysis, 22% of past marks) and Unit 4 (Network Functions, 20% of past marks).
Do AKTU Network Analysis & Synthesis questions repeat?
Yes. On average 58% of the marks in each newer BEE403 paper came from questions already asked in an earlier paper, and 19 questions have appeared in more than one paper.
How is this list made?
Every question from the 4 papers (2021-22–2025-26) 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.
