| Overall | Model | Subject | Type | Stage | Topic / Paper | Language | Syllabus | Template | Answers | Notation | Timing | Comments |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| 6.9 | DeepSeek V4 Pro | History | Quiz | 5-1 | ancient-civilisations | 9.0 | 2.0 | 4.0 | 8.0 | 10.0 | 9.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on modern history (1870s onwards), specifically European control in SEA, WWI, and WWII. This artifact covers Ancient Civilisations, which is not part of the O-Level syllabus. The questions are also too basic (recall-based) for the analytical depth required at O-Level. Question template does not follow the Source-Based Case Study (SBCS) or Essay formats required by the exam. |
| 7.0 | Qwen3.6 Plus | History | Paper | 3-1 | practice-paper-2 | 9.5 | 9.0 | 5.0 | 8.5 | - | 5.0 | The paper fails to follow the O-Level Paper 2 format. Real Paper 2 consists of Source-Based Case Studies (SBCS) and Essays. This artifact provides only short-answer/structured questions and 'scaled-down' 3-mark essays, which does not prepare students for the actual exam depth or AO3 requirements. The difficulty is too low for O-Level standards. |
| 7.2 | Gemma 4 31B | History | Quiz | 3-0 | ancient-civilisations | 9.5 | 2.0 | 7.0 | 6.0 | 10.0 | 8.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on Southeast Asia, Europe, and the Cold War; it does not cover Ancient Civilisations. The quiz content is historically interesting but irrelevant to the specified exam context. Question templates for Source-Based Analysis are generally good, but the lack of actual source texts (only descriptions provided) makes the quiz unusable for practice. Answers are provided as points rather than full model essays. |
| 7.2 | Gemma 4 31B | History | Quiz | 5-1 | ancient-civilisations | 9.5 | 2.0 | 4.0 | 8.5 | 10.0 | 9.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on modern history (1870s onwards, e.g., SEA, WWI, WWII, Cold War), whereas this quiz covers Ancient Civilisations which is not in the provided syllabus. Question formats also lack the required Source-Based Case Study (SBCS) structure essential for O-Level History. |
| 7.3 | Claude Sonnet 4 | Elementary Mathematics | Quiz | 5-1 | geometry-trigonometry | 10.0 | 9.0 | 8.0 | 6.0 | 5.0 | 8.0 | Major issues with mathematical accuracy in the answer key. Question 12(c) fails its own proof, and 12(d) has a calculation error. Question 11(c) is ambiguous. Question 13(b) calculation is inconsistent with the provided steps. Notation is inconsistent, using plain text instead of proper LaTeX for square roots and fractions. Difficulty is uneven due to these logical errors. |
| 7.3 | DeepSeek V4 Pro | Additional Mathematics | Paper | 3-1 | practice-paper-2 | 10.0 | 9.0 | 8.0 | 6.0 | 9.0 | 5.0 | Major failure in mathematical consistency. Questions 7, 8, and 10 contain logically impossible or contradictory conditions (e.g., perpendicularity that does not exist, inconsistent simultaneous equations, and imaginary tangents). The answer key identifies these errors but the paper itself is unusable for practice. Difficulty is uneven due to these logical breaks. |
| 7.3 | Legacy generator | Additional Mathematics | Quiz | 3-0 | graphs-coordinate-geometry | 10.0 | 8.0 | 7.0 | 4.0 | 9.0 | 9.0 | Major failure in answer key quality: the model's internal monologue/recalculations are visible, showing it realized the questions it generated do not match the answers it provided (e.g., Question 1 and 7). This makes the answer key unusable. Syllabus adherence is mixed as it includes Calculus (differentiation) in a 'Graphs and Coordinate Geometry' quiz. Difficulty is uneven due to mathematical inconsistencies. |
| 7.6 | Gemma 4 31B | English | Quiz | 5-1 | composition-situational-writing | 9.5 | 8.5 | 6.0 | 9.0 | 10.0 | 4.0 | The quiz focuses on theory/knowledge rather than the actual O-Level task of writing based on a visual text. The difficulty is too low for O-Level as it asks for definitions/identification rather than application in a 250-350 word composition. Exam format is incorrect: the duration (2h) and marks (100) do not align with the actual Paper 1 Section B (30 marks). Missing the required visual text component essential for Situational Writing. |
| 7.6 | Gemma 4 31B | History | Quiz | 5-1 | singapore-southeast-asia | 10.0 | 10.0 | 4.0 | 9.0 | - | 6.0 | The quiz fails to follow the O-Level History exam format, which is heavily weighted toward Source-Based Case Studies (SBCS) and specific essay structures. This artifact is a generic knowledge quiz. Section A is too long for O-Level standards, and Section C lacks the required 'Levels of Response' marking depth. Difficulty is uneven: Section A is very easy, while Section C is quite demanding. Timing is unrealistic for the volume of writing required in 90 minutes. |
| 7.7 | DeepSeek V4 Pro | History | Quiz | 3-0 | ancient-civilisations | 9.5 | 6.0 | 7.5 | 8.5 | - | 8.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on modern history (1870s onwards), whereas this quiz covers Ancient Civilisations which is not in the current syllabus. While the question structure (SBQ/Essay) mimics the exam format, the content is irrelevant to the actual O-Level curriculum. Difficulty is uneven, with Section D being too simplistic for O-Level standards. |
| 7.7 | Legacy generator | Physics | Quiz | 3-0 | electricity-magnetism | 9.5 | 6.0 | 7.0 | 9.5 | 5.0 | 10.0 | Major syllabus misalignment: Question 7 (Hydraulic Jack) belongs to Pressure/Mechanics, not Electricity/Magnetism. Difficulty is uneven, mixing very simple recall with complex logic. Notation for math and units is inconsistent, using plain text instead of LaTeX for subscripts and powers. |
| 7.7 | Qwen3.6 Plus | History | Quiz | 5-1 | ancient-civilisations | 9.5 | 4.0 | 6.0 | 8.5 | 10.0 | 9.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on modern history (1870s onwards), specifically SEA, WWI, and WWII. This quiz covers Ancient Civilisations, which is not in the O-Level syllabus. While the question skills (Source-Based, Essay) mimic the exam format, the content is irrelevant to the actual exam. Difficulty is uneven, ranging from very simple recall to higher-order analysis. |
| 7.8 | Gemma 4 31B | Elementary Mathematics | Paper | 3-1 | practice-paper-3 | 9.5 | 9.0 | 7.0 | 8.5 | 9.0 | 8.0 | Major issue: many questions (e.g., 10, 13, 15, 18) rely on diagrams that are not provided, making them unsolvable. The model includes 'thinking aloud' artifacts and self-corrections within the question text (e.g., Q11, Q14) which must be removed. Difficulty is uneven, ranging from very basic to complex geometry. Answer key is helpful but contains the same internal monologue/corrections found in the questions. |
| 7.8 | Gemma 4 31B | History | Quiz | 5-1 | source-based-skills | 9.5 | 9.0 | 7.0 | 8.5 | - | 5.0 | The quiz relies entirely on text descriptions of sources rather than actual images/cartoons, which is a major deviation from O-Level History SBQ practice. The question count (20 questions) is far too high for a 90-minute paper, making it impossible to complete within the timeframe. Question templates for SBQ (e.g., 'How far do you agree') are present but the structure of the paper does not match the actual O-Level Section A/B weighting/format. |
| 7.8 | Qwen3.6 Plus | History | Quiz | 3-0 | ancient-civilisations | 9.5 | 4.0 | 7.0 | 8.5 | 10.0 | 9.0 | Major syllabus misalignment: The O-Level History syllabus (2174) focuses on modern history (1870s onwards, e.g., SEA, WWI, WWII, Cold War). This quiz covers Ancient Civilisations, which is not part of the current O-Level History syllabus. While the question quality and source-based skills are good, the content is irrelevant to the specific exam context provided. Difficulty is uneven, mixing very simple recall with complex source analysis. |
| 7.9 | Legacy generator | English | Quiz | 3-0 | comprehension | 9.0 | 7.5 | 6.0 | 8.0 | 10.0 | 9.0 | The quiz is significantly easier than actual O-Level English Paper 2. The texts are too short and the questions lack the depth of inferential and evaluative complexity required for the 1184 syllabus. Section C introduces writing tasks that resemble lower secondary or school-based assessments rather than the rigorous Paper 2 structure. Marks and timing are provided, but the content does not match the weightage or complexity of the exam-derived source. |

Excellent coverage of FIFO, AVCO, and inventory ratios. The marking scheme is detailed with clear step-by-step workings. Question 11 uses a table format which is standard for O-Level accounting records. Minor note: The total marks (50) and duration (45 mins) are slightly different from the standard 3-hour full paper, but appropriate for a topical quiz. |
| Claude Sonnet 4 | Quiz | 5-1 | Additional Mathematics | graphs-coordinate-geometry | 8.2 | Yes | 10.0 | 9.0 | 7.0 | 9.0 | 8.0 | 10.0 | 6.0 | 7.0 | 8.0 | - | - | appropriate | The quiz covers relevant topics but includes a major logical error in the answer key for Question 6, where the model struggles with the tangency condition. The exam format is slightly off as O-Level Amath papers are typically 90 marks and longer; this is more of a topical worksheet. Question 12c requires a sketch but lacks a provided grid/space. Notation is excellent. |
| Claude Sonnet 4 | Quiz | 5-1 | Biology | cells-biomolecules | 9.6 | Yes | 10.0 | 10.0 | 9.0 | 10.0 | 9.0 | 10.0 | 9.0 | 9.5 | 10.0 | - | - | appropriate | High quality quiz.

However, it relies heavily on text-based circuit descriptions (e.g., Question 6) which should ideally be diagrams. Question 1 has a calculation error in the answer key (0.36A vs 0.32A). Notation for resistance and units is plain text rather than LaTeX. |
| DeepSeek V4 Pro | Paper | 3-1 | Principles of Accounts | practice-paper-1 | 9.8 | No | 10.0 | 10.0 | 9.5 | 10.0 | 10.0 | 10.0 | 10.0 | 9.0 | 9.5 | - | - | appropriate | High quality paper. Excellent adherence to O-Level Principles of Accounts syllabus, specifically regarding inventory valuation (FIFO/AVCO) and error analysis. Formatting, marks, and timing are consistent with Paper 1 standards. Answer key provides clear, logical working steps and marking schemes. Minor note: Question 6(d) is slightly brief for a 2-mark evaluation but acceptable. |
| DeepSeek V4 Pro | Paper | 3-1 | Principles of Accounts | practice-paper-2 | 9.7 | No | 10.0 | 10.0 | 9.5 | 10.0 | 9.5 | 10.0 | 9.0 | 10.0 | 9.0 | - | - | appropriate | High quality paper. Excellent coverage of inventory costing (FIFO/AVCO), adjustments, and ratios. The answer key is detailed and provides clear marking schemes. Minor discrepancy: Paper 2 is stated as 2 hours in syllabus but 1 hour 15 mins in the artifact; however, the content density is appropriate for a practice assessment. |
| DeepSeek V4 Pro | Paper | 3-1 | Principles of Accounts | practice-paper-3 | 9.6 | No | 10.0 | 10.0 | 9.5 | 10.0 | 9.0 | 10.0 | 9.5 | 9.0 | 9.0 | - | - | appropriate | High quality paper. Follows O-Level Paper 2 structure well. Note: The trial balance in Question 2 is intentionally/accidentally unbalanced, which the answer key acknowledges, but this might confuse students if not clearly labeled as a 'suspense account' scenario in the question itself. Calculations and marking schemes are detailed and follow standard accounting notation. |
| DeepSeek V4 Pro | Paper | 3-1 | Principles of Accounts | practice-paper-4 | 9.7 | No | 10.0 | 10.0 | 9.5 | 9.0 | 10.0 | 10.0 | 10.0 | 9.5 | 9.0 | - | - | appropriate | High quality paper. Follows O-Level 7087 syllabus closely, including specific scenario-based requirements and ratio analysis. The trial balance and inventory tables are well-structured. The answer key provides excellent step-by-step workings and clear marking schemes. Minor truncation at the very end of the SFP answer key, but the core content is complete. |

While the topic is in the syllabus, it is not a statistics/probability topic. Section A is appropriate for O-Level Amath. Difficulty is uneven, mixing very simple recall with calculus-based modeling. |
| Gemma 4 31B | Quiz | 3-0 | Biology | cells-biomolecules | 9.5 | Yes | 10.0 | 10.0 | 9.0 | 9.0 | 10.0 | 10.0 | 9.5 | 9.0 | 9.0 | - | - | appropriate | High quality content. The quiz and exam follow the O-Level structure well. Major issue: Question 4 in the exam paper relies on a graph that is only described in text (placeholder) rather than being provided as an image.
