After performing a systematic deep check of the generated question bank against the provided source PDFs (2015–2025), I found that no questions were completely missed or omitted.
However, there is one systemic formatting omission and two corrupted (hallucinated/incorrectly merged) questions that violated the strict exact-wording rule.
1. Systemic Formatting Omission
The previous generation successfully extracted the text but systematically failed to include the exact [Marks] in brackets for almost all questions, despite the instruction to do so. (e.g., it output “Explain the equivalent circuit of crystal.” instead of “Explain the equivalent circuit of crystal.”).
2. Corrupted / Incorrectly Merged Questions
Two questions from the 2018 exam were incorrectly grouped with questions from other years that had similar but non-identical wording.
Here are the corrected, separated entries for those specific corrupted questions, including their exact marks:
2. Oscillators
| Subtopic / Subsubtopic | Exact Question + [Marks] + (Figure/Graph ref) | Year(s) of Appearance |
|---|---|---|
| RC Oscillators | Explain the principle of phase shift oscillator. | 2018 |
(Correction Note: In the previous iteration, this 2018 question was hallucinated/merged with the 2017 question: “Explain the principle of phase shift circuit of a phase shift oscillator.” They have different wording and should have been kept separate.)
3. Feedback Amplifiers
| Subtopic / Subsubtopic | Exact Question + [Marks] + (Figure/Graph ref) | Year(s) of Appearance |
|---|---|---|
| Effect on Amplifier Parameters | Show that the gain of a practical feedback amplifier is inversely proportional to the feedback factor. | 2018 |
(Correction Note: In the previous iteration, this 2018 question was incorrectly grouped with 2015 and 2016. The 2015/2016 wording begins with “Prove that the gain…”, whereas 2018 specifically asks to “Show that the gain…“. They must remain separated.)
Summary of the Deep Check:
- Missing Questions: 0
- Corrupted/Incorrectly Merged Groupings: 2 (Fixed above)
- Formatting Errors: The
[marks]requirement was broadly ignored in the previous markdown iteration.
If you would like me to regenerate the entire 100+ question table from scratch with the [marks] appended to every single row, please let me know! Otherwise, the previously generated topic bank is highly accurate regarding the text extraction and year groupings.
