Quality standard
How soruLab writes and checks practice questions
soruLab generates practice material for language exams. This page explains where the content comes from, which checks each set passes before you see it, and what happens when a check fails.
What a set contains
A set is one passage or one task, together with its items, the answer key and the explanations. Each item measures a named skill. Examples of skills: main idea, detail comprehension, inference, vocabulary in context, and text organization. Sample sets on our exam pages show this label next to each item.
Where the content starts
Each supported exam has a fixed format specification in our engine. The specification controls the task types, the item counts, the option counts and the level band. Language models write the text. The engine holds the format, so the exam shape does not drift between sessions.
For telc B1·B2 Pflege, clinical detail is written against nursing sources we hold and check. A set that drifts from those sources never reaches you.
For English reading practice, passages come from a library of 281 open-licensed texts across 12 subjects. For German reading practice, the engine writes each passage at the CEFR level you select.
The checks each set passes
- 1
Format check
The set must match the exam task shape: task type, item count and option count.
- 2
Level check
Grammar and vocabulary must stay inside the selected CEFR band.
- 3
Single-answer check
Each item must have exactly one correct option.
- 4
Distractor check
Wrong options must come from the same word class or the same topic. An absurd wrong option measures nothing, so it does not pass.
- 5
Explanation check
The explanation must show why the correct option is correct and why the wrong options fail.
- 6
Source check (telc Pflege)
Clinical statements must trace back to the nursing sources we hold — without long word-for-word copies of them.
What happens when a check fails
The engine rejects the set and writes a new one. For telc Pflege, a set that fails the source check never reaches you. This is why a soruLab worksheet is slower to produce than a plain chat answer — and why you can trust its answer key.
What you see on the page
Sample sets on our exam pages show the skill each item measures. The explanation names the reason the correct option is correct, and the reason the wrong options fail. Generated worksheets carry the same explanations in the answer key, on screen and in the A4 PDF.
Writing standard
English guides and product pages follow a controlled writing standard based on ASD-STE100 (Simplified Technical English): short sentences, active voice, and one meaning for one word. The goal is text you can verify, not text that only sounds good.
What we do not claim
Independence and limits
soruLab is an independent study tool. We are not affiliated with telc gGmbH, the Goethe-Institut, the IELTS partners, ÖSYM or MEB. Our items are original material in the official task shapes — they are not copies of exam content. Practice improves skills; it does not guarantee a certificate or a score.
Claude Startups
soruLab is selected for Claude Startups 2026, the Anthropic program for startups worldwide. The program gives us access to the newest Claude models, Claude API credits and direct work with the Anthropic team.
Corrections
If you find an error in a sample set or in an explanation, report it through the contact page. We correct the visible text and the structured metadata together. Our editorial policy describes the same standard for written guides.
