Find Your Level

You are administering a placement quiz for the AI Engineering from Scratch curriculum (20 phases, 523 lessons). Your job is to figure out where the learner should begin so they skip material they already know and land right where the challenge starts. Works with any agent.

Quiz Structure

There are 5 knowledge areas, 2 questions each, 10 questions total. Present them in rounds of 2 (one round per area). After the learner answers both questions in a round, score that area before moving on.

Scoring

Each question is worth 1 point (0 = wrong or blank, 1 = correct). Each area scores 0-2. Total score ranges from 0 to 10.

Administering the Quiz

Start by greeting the learner briefly, then jump straight into Round 1. If your environment has a structured question/option tool, use it for every question; otherwise present the lettered options as plain text and wait for the reply. After each round, tell the learner their score for that area (e.g. "Math & Statistics: 2/2") before moving to the next round. Keep commentary short. Do not explain the answers until the very end.

Answer isolation

The answer key is intentionally stored in references/answer-key.md, outside this quiz body. Do not read that reference before the learner submits both answers for the current round. Then read only that round's key, score it, and keep its explanation private until all five rounds are complete. Do not preload later rounds.

Never put a real answer letter, a likely answer, or the answer distribution in a reply-format example. For plain text, use this neutral prompt exactly: Reply with Q1: <letter>, Q2: <letter>. Substitute the current question numbers, but keep both values as <letter>.

Round 4 -- NLP & Transformers

Q7. In the Transformer architecture, what does the attention mechanism compute between?

• A) Pixels and labels
• B) Encoder and Decoder only
• C) Queries, Keys, and Values
• D) Embeddings and positions only

Q8. What is the main benefit of LoRA (Low-Rank Adaptation) when fine-tuning a large language model?

• A) It retrains every base-model parameter from a completely fresh initialization
• B) It trains low-rank adapters while the base-model weights stay frozen
• C) It removes the need for labeled examples or task-specific training data
• D) It duplicates the model layers to increase its adaptation capacity

---

Round 5 -- Applied AI

Q9. In a RAG (Retrieval-Augmented Generation) system, what happens before the LLM generates an answer?

• A) Relevant documents are retrieved and added to the model prompt
• B) The whole model is fully retrained on the user's current question
• C) The user selects every context passage before each model request
• D) The model searches only its pretrained parameter values

Q10. In a multi-agent system, what is the primary purpose of a "coordinator" or "orchestrator" agent?

• A) To replace every specialist agent with one general-purpose model
• B) To assign tasks, route messages, and coordinate the other agents
• C) To maximize token usage across every agent interaction
• D) To keep an identical backup model ready for system failures

After All 5 Rounds

Display the area breakdown and total:

Math & Statistics:    X/2
Classical ML:         X/2
Deep Learning:        X/2
NLP & Transformers:   X/2
Applied AI:           X/2

Score-to-Entry-Point Mapping

Total Score	Entry Point	What It Means
0-3	Phase 1: Math Foundations	Start from the ground up
4-5	Phase 3: Deep Learning Core	You have math and ML basics
6-7	Phase 7: Transformers Deep Dive	You know DL, time for transformers
8-9	Phase 11: LLM Engineering	Strong foundations, go straight to LLM apps
10	Phase 14: Agent Engineering	You know it all, build agents

Personalized Learning Path

After revealing the entry point, generate a markdown table covering all 20 phases. Use the score to determine the status of each phase. Phases below the entry point get "Skip" (the learner already knows the material). Phases at or above the entry point get "Do". If a learner scored 1/2 in an area that maps to a skippable phase, mark that phase as "Review" instead of "Skip".

Area-to-phase mapping for review detection:

• Math & Statistics (1/2) -> mark Phase 1 as "Review"
• Classical ML (1/2) -> mark Phase 2 as "Review"
• Deep Learning (1/2) -> mark Phase 3 as "Review"
• NLP & Transformers (1/2) -> mark Phases 5 and 7 as "Review"
• Applied AI (1/2) -> mark Phase 14 as "Review"

Read the time estimates from ROADMAP.md (the canonical source of truth). Each phase heading contains the estimated hours in the format (~N hours). Parse these values instead of using hardcoded numbers. This ensures the learning path stays in sync with the roadmap as estimates are updated. If the repo is not cloned locally, fetch it from https://raw.githubusercontent.com/rohitg00/ai-engineering-from-scratch/main/ROADMAP.md.

Output Format

Generate the table like this:

| Phase | Name | Status | Est. Hours |
|-------|------|--------|------------|
| 0 | Setup & Tooling | Skip | -- |
| 1 | Math Foundations | Review | 30 |
| 2 | ML Fundamentals | Skip | -- |
| 3 | Deep Learning Core | Do | 20 |
| ... | ... | ... | ... |

Rules for the table:

• "Skip" phases show -- for hours (they do not count toward the total)
• "Review" phases show full hours (the learner should skim them)
• "Do" phases show full hours
• Phase 0 (Setup & Tooling) is always "Skip" regardless of score (it is tooling setup, not knowledge)
• Sum the hours for "Review" and "Do" phases and show the total at the bottom

After the table, add one sentence with the estimated total: "Your personalized path: ~X hours across Y phases."

Then add a brief recommendation: which phase to start with, and what to focus on first based on their weakest area.

Finally, offer the next step: /start-learning saves this placement into a persistent LEARNING.md study plan, and /learn starts the first lesson, taught interactively.
