Texts from A1 to B2

A1

13 texts

Short everyday scenes in the present tense.

A2

26 texts

Daily routines, separable verbs, simple connectors.

B1

39 texts

Expository texts with weil, wenn, and richer endings.

B2

26 texts

Passive, Konjunktiv, and relative clauses — the exam register.

What you practice

Solve C-Tests

Complete missing word halves in four free texts and a half simulation. The Pass includes 104 texts from A1 to B2, each written for the onSET format and chosen for what gets you to B1 — quality, not sheer volume.

Grammar for the gaps

50 lessons in 19 units, chosen by what the C-Test deletes: article and adjective endings, case after prepositions, verb forms and participles, plural endings, and small words like weil, dass, dem, and den. Every lesson shows how its topic appears as a C-Test gap.

Review mistakes

Reports separate knowledge errors from timing problems and show which grammar areas to repeat.

Simulate the exam

Practice under test-day conditions with four or eight texts: 20 gaps and five minutes per text, no going back, and an interface designed to look like the real exam.

How to prepare

Learn, practice, test. Each step uses what you missed before.

  1. Learn the format

    Start with the free lessons and a free C-Test with solutions. No account is required.

  2. Practice weak areas

    Focus on the endings, cases, and verb forms you do not yet answer reliably.

  3. Test under time

    Take a half or full simulation and compare your results across attempts.

Questions

What is onSET-Deutsch?
onSET is a C-Test with eight texts and 20 gaps per text. You have five minutes for each text. Your result maps to a CEFR level.
Why this grammar?
Because the onSET is a C-Test: every second word loses its second half. You see the start of the word; what you have to decide is usually the ending — den or dem, kleine or kleinen, wohne or wohnt. So the course focuses on endings, cases, verb forms, and small words rather than writing or speaking topics.
Why 104 texts and not hundreds?
Because more texts alone do not earn more points. Every text is aimed at getting you to B1 and linked to the grammar course: when you miss a gap, you see the rule behind it and practice it on purpose, instead of repeating the same mistakes on new texts.
What can I use for free?
Nine grammar lessons across the first three units, four C-Test texts with solutions, one timed half simulation, and the guides are available without payment.
Is this the official test?
No. onSET Prep is an independent training product. The official test is provided by the TestDaF-Institut through onset.de.
Is the Pass a subscription?
No. You pay once and keep access forever. There is no expiry date and no automatic renewal.
Are the texts official CEFR levels?
No. A1 to B2 describe the written difficulty of our practice texts. That is not an official placement and not a prediction of your exam result.
Does the course guarantee B1?
No. The course reproduces the format and helps you practice specific skills. Your result depends on your German level and your performance on test day.
Can I use this outside Germany?
Yes. The practice runs online. The official onSET is separate and must be booked at a licensed test center; check the current worldwide center list on onset.de before you book.
