Practice¶
Full mock exams matching the format of the real paper: 24 multiple-choice questions across the four sections, 4 marks each, 90 minutes, no negative marking.
- 90 minutes each
- Instant scoring
- Five full mocks
How to take a mock
- Set a 90-minute timer. No pausing, no reference material.
- Answer every question — no negative marking means blanks are strictly worse than guesses.
- Use scratch paper for the numerical questions (PQ math, top-k∩top-p, Levenshtein). Don't trust intuition on arithmetic.
- Flag hard questions and return to them after Q24.
- Grade honestly. For every wrong answer, reread the corresponding Learn guide block before your next mock.
Available mocks¶
| Mock | Coverage | Difficulty | Length |
|---|---|---|---|
| Mock Exam 1 | All 4 sections, 24 questions | Matches sample paper | 90 min |
| Mock Exam 2 | All 4 sections, 24 questions | Matches sample paper | 90 min |
| Mock Exam 3 | All 4 sections, 24 questions | Matches sample paper | 90 min |
| Mock Exam 4 | All 4 sections, 24 questions | Matches sample paper | 90 min |
| Mock Exam 5 | All 4 sections, 24 questions | Slightly harder — challenge round | 90 min |
Suggested order
Work through Mock 1 first, then Mock 3, then Mock 4, then Mock 2, and save Mock 5 for last. This mixes original scenarios with the sample-paper style paper so you calibrate to both.
Section weighting (as tested)¶
The exam is roughly balanced across four sections. Each has 6 questions × 4 marks = 24 marks:
| Section | Coverage | Lectures |
|---|---|---|
| 1 | ML foundations & model architecture | 1, 2 |
| 2 | LLM decoding, APIs, tooling, evaluation, safety | 4, 5, 6 |
| 3 | Prompting techniques & NLP metrics | 7, 8, 5 |
| 4 | Vector indexing & RAG security | 11, 12 |
After you finish a mock¶
Grade the whole thing before looking at any explanations. Then for each question:
- Got it right, confident: Move on.
- Got it right, guessed: Read the answer explanation — that's a knowledge gap disguised as a win.
- Got it wrong: Read the answer explanation, then open the linked Learn guide section and reread it.
Track your weakest section. Spend the next study block there.
