After performing a meticulous deep-check of the provided syllabus-aligned question bank against the raw exam papers from 2015 to 2025, I found two issues.
One question was completely omitted (missed), and another was corrupted due to improper merging (it was grouped with a similar question from a different year despite having different numerical values).
Here are the missing and corrupted questions, formatted in the exact tabular structure as requested:
Missing & Corrupted Questions
Topic 3: Boolean Algebra & Logic Gates
| Subtopic | Exact Question | Year(s) of Appearance | Issue Type |
|---|---|---|---|
| Logic Circuit Simplification & Implementation | Simplify the following logic circuit as shown in Fig. 2(b). (Figure Fig. 2(b)) (12) | 2017 | Missing (This was omitted in the previous output. It differs slightly in wording from the 2016 and 2019 variants of the same figure) |
Topic 6: Registers & Counters
| Subtopic | Exact Question | Year(s) of Appearance | Issue Type |
|---|---|---|---|
| Registers | The content of a 5-bit shift register is initially 11010. The register is shifted six times to right with serial input 110100. What will be the content of the register after each shift? (10) | 2024 | Corrupted / Improperly Merged (This was previously grouped with the 2020 question. However, the 2020 question has values 10110 and 101100, while the 2024 question uses 11010 and 110100. They cannot be merged) |
Aside from these two specific items, the rest of the generated question bank successfully preserved every other question with verbatim accuracy, correct figure references, and proper year groupings.
