The Sprachbausteine in telc B2 are two parts of ten gaps each: Teil 1 tests grammar with three options per gap, Teil 2 tests vocabulary with fifteen words for ten gaps. Every correct answer is worth 1.5 points, 30 in total. Understand how these tasks are built and you solve them faster and more safely, because every gap tests a single decision.
By Ela Zakrzewska, telc B2 examiner for over 20 years. Hundreds of letters marked against the official criteria.
The Sprachbausteine are the most underrated part of telc B2. Candidates spend weeks on letters and listening texts and treat the 20 gaps as an afterthought, as if they were a grammar quiz from class.
That is an arithmetic mistake. 30 points hang on this part, and you pass the written exam from 135 of 225. For many candidates who fail narrowly, the difference sits right here: not in the letter, but in eight or nine gaps given away.
And it is a mistake about what the task is. The Sprachbausteine are not a classroom grammar test. They are constructed items with an internal logic, and once you know that logic you play a different game: you stop hunting for the right answer and start eliminating the wrong ones.
How are the telc B2 Sprachbausteine structured?
Both parts run inside the 90 shared minutes with the reading section. How you divide that time is up to you, and so is the order. telc itself suggests about 15 minutes for Teil 1 and 20 for Teil 2, and allow roughly 10 minutes for transferring all your answers to the Antwortbogen, the answer sheet.
| Teil 1 | Teil 2 | |
| Text | Gap text, usually an e-mail | Magazine text of general interest |
| Gaps | 10 | 10 |
| Options | 3 per gap, one correct | 15 words for all gaps, 5 left over |
| Tests | Grammar | Vocabulary |
| Points | 1.5 per gap, 15 total | 1.5 per gap, 15 total |
The split is sharper than it looks, and it is stated in telc's own preparation tips: Teil 1 tests "Deklinationen, Artikelsetzung, Präpositionen, Pronomen, Konjunktionen, Pronominaladverbien, Verben, Partikeln", declensions, articles, prepositions, pronouns, conjunctions, pronominal adverbs, verbs, particles, in short every word class, grammatically. Teil 2, by contrast, does not check whether you can decline and conjugate, but "ob Ihr Wortschatz dem erwarteten Niveau entspricht", whether your vocabulary matches the expected level.
One part tests forms, the other tests meanings. Approach both with the same method and you waste time in one of them.
The logic of Teil 1: every gap is one single decision
A Teil-1 item has three options, and those three almost never differ in three dimensions at once. They differ in one: case, gender, position, or Rektion, the fixed preposition a verb governs. The item is not asking "can you speak German?". It is asking "which of these three forms fits this one slot?".
An example in the style of the exam, built by us:
Ich bedanke mich im Voraus ___ Ihre Mühe. a) über b) für c) um
All three are real German prepositions, and all three appear after verbs of thanks and feeling. Only one thing is being tested: the Rektion of "sich bedanken". If you learned "bedanken für" as one unit, this takes two seconds. If you learned prepositions as single words, you are guessing.
The solving strategy follows, and it matches telc's own tips: read the sentence first without the options. At B2 you have a feel for the language, and it often fills the gap on its own. Then compare with the options, and your answer is usually among them. Only when nothing comes do you work the other way round: look at the options and check systematically what fits for gender, number and case.
The second route is slower, but it has one advantage: two options can almost always be eliminated, because they fail at exactly the dimension being tested. In this part, eliminating is faster than knowing.
The logic of Teil 2: five words are traps
Teil 2 looks more generous and is stricter. Fifteen words for ten gaps means: five of the offered words fit nowhere. They are not chosen at random. They sit semantically close to the correct ones, same word class, similar field, and that is precisely how they test whether you know words roughly or properly.
So a different order works here:
- Read the whole text once, without the word list. Your feel for the language closes some gaps on its own, and every gap you fill shrinks the list.
- Fill the certain gaps first and cross out the words you have used. Every crossed-out word makes the rest easier.
- Look at the surroundings of the gap, not at the gap itself. The decision almost always turns on the connection: which verb the noun demands, which preposition follows, which word belongs in that fixed expression. What is tested are collocations, not definitions.
- Leave no gap empty at the end. That is not a Knaxx opinion, it is telc's official tip: "Lassen Sie keinesfalls eine Lücke leer ... Andernfalls vertun Sie Ihre Chance und verschenken Punkte." Never leave a gap empty, otherwise you throw away your chance and give away points. There is no penalty for wrong answers. A guessed gap can earn 1.5 points; an empty one cannot.
The arithmetic that makes this part look smaller than it is
Twenty items, thirty points, time shared with the reading. Sounds minor. Now the other calculation:
You pass the written exam at 135 of 225 points. The letter brings at most 45, and the zero-point rule lurks there. Reading and listening move with the texts and with your form on the day. The Sprachbausteine are the only part of the written exam that is fully trainable: a bounded task type, recurring test dimensions, no surprise topics, no examiner discretion.
Secure 24 of the 30 points here instead of 12 and you have often collected the distance between failing and passing before the letter begins. And the investment is small, because the same twenty grammar dimensions and collocation patterns recur in every test version.
What actually recurs in Teil 1
From twenty years of teaching, offered as an examiner's observation and not as a telc list: the gaps keep circling the same decisions.
- Verbs with a fixed preposition (sich bedanken für, sich beschweren über, teilnehmen an), the single most frequent category
- Connectors and their word order: obwohl versus trotzdem, denn versus weil, je ... desto
- Pronominal adverbs: darauf, darüber, womit, worauf
- Case after prepositions, especially the two-way prepositions and the genitive prepositions wegen, trotz, während
- Relative pronouns in all cases, especially with a preposition: mit dem, auf die, deren
- Particles and adverbs that differ only in nuance: erst versus nur, schon versus noch
If you want to practise with focus, practise these six fields. Not because the rest never appears, but because these six appear several times in almost every version.
The time plan inside the 90 minutes
The 90 minutes belong to reading and Sprachbausteine together, and the order is yours. telc itself advises deciding before the exam whether you start with the easier tasks or the ones worth more points.
A split that has proven itself:
- Sprachbausteine first, about 25 to 30 minutes. They are short, mechanical, and your concentration is freshest at the start. After that, 30 points are banked before the long reading texts begin.
- Then reading, about 50 minutes, in the official recommendation: global, detailed, selective.
- The last 10 minutes: transfer. All answers onto the Antwortbogen. Those 10 minutes are in telc's own tips, and they are the ones most often forgotten. A correct answer that never reaches the answer sheet does not exist.
Whether you start with the Sprachbausteine or the reading is a matter of type. The buffer for transferring is not negotiable.
What you can do right now
- Run one complete Sprachbausteine round under time, both parts in 35 minutes, and count honestly: how many of the 30 points stand?
- Sort your mistakes into the six fields above. They almost always cluster in two of them, and then you know what to practise.
- Build a verbs-with-prepositions list from your own mistakes, not from a ready-made table. Twenty entries are enough to start.
- Train the order: sentence without options first, then compare. That is the skill that holds under time pressure.
- Measure yourself under real conditions: in the Knaxx mock exam, the Sprachbausteine run inside the 90 minutes exactly as on exam day. Take your first exam free at app.knaxxdeutsch.de, no credit card, no account.
Crack the logic of the gaps and they become the cheapest 30 points in the exam.
FAQ: telc B2 Sprachbausteine
How many points are the Sprachbausteine worth?
30 of the 225 points in the written exam: two parts of ten gaps each, every correct answer worth 1.5 points. With a pass mark of 135, this part decides the result more often than its size suggests.
How much time do I have for the Sprachbausteine?
There is no separate slot. Reading and Sprachbausteine share 90 minutes, and you decide how to split them. The official recommendation: Teil 1 in about a quarter of an hour, Teil 2 in twenty minutes, and a ten-minute buffer at the end so every answer reaches the Antwortbogen.
What is the difference between Teil 1 and Teil 2?
Teil 1 tests grammar: ten gaps, three options each, covering declension, prepositions, pronouns, connectors and other form decisions. Teil 2 tests vocabulary: ten gaps, fifteen offered words, five left over. There it is not about forms but about whether your vocabulary matches the level.
Do wrong answers cost points?
No. That is why telc's official advice stands: leave no gap empty. Guessing costs nothing and can hit; an empty gap is the only guaranteed error.
Should I start with the Sprachbausteine or the reading?
Your choice, and telc recommends making it before the exam rather than in the room. There is a good case for the Sprachbausteine first: they are short, predictable, and they bank 30 points before your concentration goes into the long texts.
Is feel for the language enough, or do I need to drill grammar?
Both have their place, and telc's tips describe exactly these two routes: fill the gap without the options and then compare, or check systematically by gender, number and case. At B2, feel carries most gaps. Practising the six recurring grammar fields closes the rest.
