How to Skip Lessons in the AI Engineering Curriculum: A Placement Guide for Experienced Learners

Run the /find-your-level command to take a ten-question placement quiz that maps your existing knowledge to specific entry points (Phases 1, 3, 7, 11, or 14) in the 20-phase curriculum, generating a personalized roadmap that marks mastered phases as "Skip" and weak areas as "Review."

The rohitg00/ai-engineering-from-scratch repository structures its content as a stacked sequence of 20 dependent phases where each lesson builds upon the previous. If you already understand Math & Statistics, Classical ML, or Deep Learning, you can skip lessons in the AI Engineering curriculum by using the built-in placement system rather than manually guessing where to start.

Understanding the Stacked Curriculum Structure

The curriculum follows a strict dependency graph defined in README.md. Each phase relies on concepts from all previous phases, creating a foundation that prevents gaps in knowledge. The repository warns: "Skip ahead if you already know the lower layers, but don't skip and then wonder why something at the top is breaking."

This architecture means you cannot arbitrarily jump to Phase 10 without verifying mastery of Phases 1-9. The system enforces this by treating the curriculum as a directed acyclic graph where each node must be satisfied before ascending.

Using the /find-your-level Placement Quiz

The repository provides a dedicated placement quiz accessible via the /find-your-level command. This skill is defined in .claude/skills/find-your-level/SKILL.md and evaluates five critical knowledge areas:

• Math & Statistics
• Classical ML
• Deep Learning
• NLP & Transformers
• Applied AI

The quiz presents ten multiple-choice questions (two per area) that assess your current expertise level. You can invoke this skill in any supported agent including Claude, Cursor, Codex, OpenClaw, or Hermes.

How the Scoring System Maps to Entry Points

The placement quiz uses a 0-2 point scale for each knowledge area, yielding a total score between 0 and 10. This score maps directly to specific entry points in the curriculum.

The Five Knowledge Areas

Each area corresponds to specific phases in the ROADMAP.md. The mapping ensures that partial knowledge in one domain does not falsely qualify you for advanced material in related domains.

1. Math & Statistics (Phases 1-2)
2. Classical ML (Phases 3-6)
3. Deep Learning (Phases 7-10)
4. NLP & Transformers (Phases 11-13)
5. Applied AI (Phases 14-20)

Score-to-Entry-Point Mapping

The skill logic in SKILL.md translates your total score to one of five entry points. This mapping ensures you enter the curriculum at the precise phase where your knowledge gaps begin.

• Score 0-2: Start at Phase 1 (Math Foundations)
• Score 3-4: Start at Phase 3 (Deep Learning Core)
• Score 5-6: Start at Phase 7 (NLP Foundations)
• Score 7-8: Start at Phase 11 (Applied AI Basics)
• Score 9-10: Start at Phase 14 (Advanced Systems)

Generating Your Personalized Learning Path

After calculating your score, the system generates a markdown table showing the status of each phase. According to the skill definition in .claude/skills/find-your-level/SKILL.md, the logic assigns one of three statuses to every phase in the 20-phase sequence.

• Skip: All phases below your entry point receive this status
• Do: The entry point phase itself and any required subsequent phases
• Review: Phases where you scored only 1 out of 2 in the corresponding knowledge area

The table includes hour estimates pulled directly from ROADMAP.md, ensuring your study plan reflects the current canonical time requirements. These estimates appear next to each phase in the format (~30 hours) or similar.

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

The skill also outputs a summary sentence estimating your total commitment, such as: "Your personalized path: ~50 hours across 7 phases." This helps you plan your schedule before beginning the work.

Running the Skill in Different Environments

You can execute the placement quiz through multiple interfaces depending on your setup.

Command Line Interface

Invoke the skill directly in any supported agent console:

/find-your-level

The interactive Q&A proceeds in the terminal, then displays the markdown table with your personalized results.

Python API Integration

Embed the skill in custom automation scripts using the Claude API:

import json, requests

def run_find_your_level():
    payload = {"messages": [{"role": "user", "content": "/find-your-level"}]}
    resp = requests.post(
        "https://api.anthropic.com/v1/complete",
        headers={"x-api-key": "YOUR_API_KEY"},
        json=payload,
    )
    return resp.json()["completion"]

print(run_find_your_level())

Filtering Your Results

Generate a concise reading list from the output table by filtering for "Do" and "Review" statuses:

# Assuming the markdown table is stored in $TABLE

grep -i "Do\|Review" <<< "$TABLE" | awk -F'|' '{print $2,$3}'

This outputs only the phases requiring your attention.

Why the Placement Quiz Prevents Knowledge Gaps

The /find-your-level skill ensures you do not miss hidden dependencies that could break later phases. By testing foundational concepts across all five knowledge areas, it verifies that you possess the prerequisite understanding even if you plan to skip lessons in the AI Engineering curriculum.

The hour-parsing logic pulls estimates directly from ROADMAP.md, ensuring your time projections stay synchronized with any curriculum updates. The web UI generated by site/build.js also exposes this functionality for browser-based access.

Summary

• The curriculum contains 20 dependent phases requiring verified prerequisites before advancing.
• Run /find-your-level to take a ten-question placement quiz covering five knowledge areas.
• The system generates a personalized markdown table marking phases as Skip, Do, or Review based on your 0-10 score.
• Entry points map to Phases 1, 3, 7, 11, or 14 depending on your total score.
• Hour estimates are pulled dynamically from ROADMAP.md via the skill's parsing logic.
• You can invoke the skill via CLI, Python API, or the web interface built by site/build.js.

Frequently Asked Questions

Can I manually skip phases without taking the quiz?

While you could manually edit your progress, the repository strongly advises against it. The README.md explicitly warns that skipping without verification leads to confusion when advanced concepts fail due to missing foundations. The placement quiz ensures you actually possess the required knowledge rather than assuming it.

What happens if I score 1 out of 2 in a knowledge area?

When you score 1 out of 2 in any area, the skill marks the corresponding phase as Review rather than Skip. This indicates you have partial knowledge but should revisit specific concepts before proceeding. The system prioritizes filling gaps over speed to prevent future debugging confusion.

How accurate are the time estimates in ROADMAP.md?

The hour estimates in ROADMAP.md serve as the canonical source of truth for the curriculum. The skill parses these values directly from the file (e.g., (~30 hours) for Phase 1), ensuring your personalized projections always match the current repository state. These estimates assume approximately 10-15 hours of focused study per week.

Can I retake the placement quiz if my skills improve?

Yes, you can invoke /find-your-level multiple times. The skill statelessly evaluates your current responses, so retaking it after completing additional training will generate an updated roadmap with new Skip/Do/Review designations. Store your previous results to compare progress between attempts.
