Module 2 and adaptive papers: what teachers need to know

On the digital SAT, the questions a student sees in the second half of each section depend on how they did in the first half. For a teacher, that makes Module 1 the most important part of the paper.

Updated 4 October 2026 · 4 min read · from the team behind Colorbook, a free digital SAT practice tool.

Each section of the digital SAT has two modules. Module 1 is a broad mix of difficulty; Module 2 is either harder or easier, depending on how the student did in Module 1. Colorbook's adaptive class mocks work the same way, so you can rehearse that structure with a class and see where each student landed.

How the real test adapts

Reading and Writing has two modules of 27 questions; Math has two modules of 22. Everyone in a section starts with a Module 1 that mixes easier and harder questions. Once Module 1 is done, the student is given either a harder or an easier Module 2.

The practical consequence is that Module 1 matters more than it seems. A student who rushes or makes careless slips early can be routed to the easier Module 2, which limits how high their section score can go, however well they then do. For more on this, see why the first module decides your score and how the digital SAT works.

How Colorbook mirrors it

When you set up an exam-shaped class mock (English only, Math only or a full SAT) you choose how Module 2 is handled.

Harder path only

Every student gets the harder Module 2. This is useful for a strong group, for practising the hardest material, or when you want every student to have seen the same second module so you can go through it together.

Adaptive

Module 1 is marked first, and each student is then given the harder or easier Module 2 by Colorbook's routing rule:

• English: 15 or more of the 27 Module 1 questions right routes to the harder module.
• Math: 12 or more of the 22 Module 1 questions right routes to the harder module.

To be clear: this rule is Colorbook's own. The College Board does not publish its routing rule. What Colorbook's rule does reproduce is the feature that matters for practice: a weak Module 1 leads to the easier Module 2.

Same paper, or drawn from the bank

Exam-shaped papers come in two forms.

• Exam paper, same for everyone. One paper in the shape of a test form, sat by the whole class, with a harder or adaptive Module 2. Easier to discuss afterwards, because everyone saw the same Module 1.
• Random from the Colorbook bank. Each student gets their own questions. On an adaptive paper, Module 2 is drawn from the bank only after that student's Module 1 has been marked, so it is chosen for the route they actually earned. Better when students sit close together, or when some have seen your usual papers before.

Difficulty tiers

You also choose a difficulty tier for the paper: Easy, Standard, Difficult or Challenge. Standard is pitched at test-day difficulty. Easy sits below it, and Difficult and Challenge above.

Use Standard for anything you want to compare with the real test. Easy can help a group early in a course build confidence with the format; Difficult and Challenge suit strong students who need practice on the hardest questions. Do not compare scores across tiers.

What the route tells you

After an adaptive mock, each student's result shows the route they took in each section and how many Module 1 questions they got right, for example "English: harder Module 2 (19/27 in Module 1, needed 15)" and "Math: easier Module 2 (9/22 in Module 1, needed 12)". That one line says a lot.

Look at the route alongside the replay. A student who got 14 of 27 but spent four minutes on one question and guessed the last three is a pacing problem. A student who got 14 and finished with time to spare is not.

What to watch for

• Do not teach to the threshold. The 15 and 12 are Colorbook's practice rule. Use them to group students, not as targets for the real test.
• Explain the route to students. Many students do not realise Module 1 decides what comes next. Showing a student their own route is often the most persuasive argument for slowing down early.
• Compare like with like. A score on the easier route and a score on the harder route are not the same achievement, and a Challenge paper is not a Standard one.

Questions teachers ask

How does the digital SAT adapt?

Each section has two modules. Module 1 is a broad mix of difficulty. Depending on how a student does in Module 1, they get a harder or an easier Module 2.

What routing rule does Colorbook use?

In English, 15 or more of 27 Module 1 questions right routes to the harder Module 2; in Math, 12 or more of 22. This is Colorbook's own rule, not an official one.

What is the difference between harder-path-only and adaptive?

Harder path only gives every student the harder Module 2. Adaptive marks Module 1 first and gives each student the harder or easier Module 2 by the routing rule.

What do the difficulty tiers mean?

Papers can be Easy, Standard, Difficult or Challenge. Standard is pitched at test-day difficulty; Easy is below it and Difficult and Challenge are above.
