Lessons are the core unit of learning inside a course. A typical lesson takes 5–15 minutes and combines reading content with interactive exercises. When you finish a lesson, you earn XP and unlock the next one.

Lesson structure

Every lesson follows a similar structure:
1

Reading section

The lesson starts with 1–3 screens of reading content. This explains the core concept you’re about to practice. Read it carefully — the exercises will test this directly.
2

Interactive exercises

A sequence of 3–10 exercises, depending on the lesson. Each exercise type is described below.
3

Completion & XP

When you finish all exercises, you see your score, the XP you earned, and a prompt suggesting an Atlas search to apply what you just learned.

Exercise types

Multiple Choice

The most common type. You’re shown a question and 3–4 options. Select the correct one.
  • If you answer correctly: you get a green confirmation and move on
  • If you answer incorrectly: you see a red indicator and an explanation of why the correct answer is right. You’ll see a similar question later in the lesson.

Fill in the Blank

A sentence with a missing word or phrase. Type the correct answer.
  • Minor spelling differences are accepted
  • You get one attempt, then the answer is shown with an explanation

Matching

Two columns of terms or concepts. Drag items on the right to match them with items on the left.
  • All pairs must be correctly matched to proceed
  • Incorrect pairs are highlighted so you can see which ones are wrong

Ranking

A list of items you need to put in the correct order — chronological, by importance, by sequence, or by some other criterion.

Multiple Select

Like multiple choice, but more than one answer is correct. Select all that apply.

Writing Prompt (AI-graded)

A short written response to a question. These are graded by AI, which looks for:
  • Presence of key concepts
  • Logical structure
  • Appropriate length and content
You’ll get immediate feedback explaining what you got right and what could be stronger.

Scores and mistakes

Lessons track your score (correct answers) and mistakes (wrong answers). A higher score earns more XP. Mistakes don’t penalize you harshly — they trigger a second attempt at the concept later in the lesson. Perfect lesson bonus: Answer every exercise correctly on the first attempt to earn a small XP bonus on top of the standard lesson reward.

The Atlas search prompt

At the end of every lesson, there’s a suggested Atlas search — a real question that connects the lesson’s concept to current events or a real-world scenario. This step is optional, but highly recommended. It takes 2 minutes and dramatically improves retention. For example, after a lesson on UN Security Council veto mechanics, the suggested search might be: “Which countries have used the Security Council veto most recently and why?”

Picking up where you left off

If you close a lesson mid-way, your progress is not saved — you’ll restart from the beginning when you return. Plan to finish a lesson in one sitting (most take under 15 minutes).
