In telc B2 Schreiben, Konjunktiv II (the German subjunctive, used for politeness and hypotheticals) is not a grammar topic. It is a level signal. The official telc criteria do not mention it by name. Under Kriterium II (Kommunikative Gestaltung, communicative design) they assess whether your register fits and how varied your language is, and that is exactly where Konjunktiv II helps decide whether your letter sounds polite and grown-up or demanding and basic. You don't need thirty forms for this. You need six real forms, the construction würde + Infinitiv for everything else, and at least two places in your letter where they sit securely.
By Ela Zakrzewska. For over 20 years she has prepared learners for telc exams and marked their exam papers against the telc criteria.
There is a moment in marking when a letter is decided, and it comes earlier than most people think.
Two candidates write the same complaint about the same broken fridge. One writes: „Ich will mein Geld zurück.“ The other writes: „Ich würde Sie bitten, mir den Kaufpreis zu erstatten.“ Same request, same grammar knowledge behind it, a different level on the marking sheet.
The difference is not politeness as a matter of character. The difference is a form that B2 can do and B1 can't. That is exactly what Kriterium II looks at: register and range of language.
And that is why Konjunktiv II is the part of German grammar that pays off fastest for the telc B2. Not because it is hard, but because, in my experience, many candidates avoid it.
Why Konjunktiv II decides your level
Writing in the telc B2 is marked on three criteria. (telc calls the text you write a semi-formal e-mail; we keep calling it a letter here.) Kriterium II, Kommunikative Gestaltung, asks among other things: does your register fit the situation? Do you control the language an adult writer of German uses for delicate requests?
One word does not appear in the official criteria: Konjunktiv. telc does not require any particular grammatical form. It assesses range of language and whether you hit the right register.
In a complaint, a request, a refusal or a claim for a faulty product, Konjunktiv II is exactly that tool. Without it, the tone tips over. To a German reader, a letter written entirely in the Indikativ (indicative) does not read as neutral. It reads as curt:
| Without Konjunktiv II | With Konjunktiv II |
| Ich will eine Antwort bis Freitag. | Ich würde mich über eine Antwort bis Freitag freuen. |
| Schicken Sie mir die Rechnung. | Könnten Sie mir bitte die Rechnung schicken? |
| Das ist nicht akzeptabel. | Ich hätte in diesem Fall eine andere Lösung erwartet. |
| Ich habe eine Frage. | Ich hätte noch eine Frage. |
The right-hand column is not more German. It is different German, and the examiner recognises it in the very line where it stands.
To put this in proportion: a missing Konjunktiv alone does not drop your letter to zero. Each of the three criteria gets A, B, C or D, worth 5, 3, 1 or 0 points, and the total is multiplied by three. So a D in one criterion costs you that criterion's points, up to 15 of 45, not the whole letter. You only get 0 points if your text misses the topic or the task number is missing from the Antwortbogen S30 (answer sheet S30) (when you really get 0 points in Schreiben). But Kriterium II assesses your register, and in my experience Konjunktiv II is the most visible signal there. One clear distinction applies: grammar mistakes in Konjunktiv forms (for example „ich hätte gekommen“ instead of „ich wäre gekommen“) count under Kriterium III (Formale Richtigkeit, formal accuracy); choosing polite Konjunktiv forms supports Kriterium II.
The six forms you really need
German has a long list of Konjunktiv II forms. For the telc B2 letter you need six of them, securely. That is not a simplification for beginners. It is what practised writers actually use day to day.
| Verb | Konjunktiv II | What it does in a letter |
| sein | wäre | Suggestions, evaluations: Es wäre hilfreich, wenn... |
| haben | hätte | Requests, expectations: Ich hätte eine Bitte. |
| können | könnte | Polite question: Könnten Sie mir mitteilen, ob... |
| müssen | müsste | Cautious statement: Das müsste bis Montag möglich sein. |
| sollen | sollte | Recommendation: Man sollte den Termin verschieben. |
| dürfen | dürfte | Assumption, very polite: Das dürfte ein Missverständnis sein. |
Plus two that are worth it if you already know them: wüsste (Ich wüsste gern, ob...) and bräuchte (Ich bräuchte die Unterlagen bis Freitag).
You don't need more. Six forms you control are worth more in the exam room than twenty you have to think about.
würde + Infinitiv: when it's right, and when it makes you look B1
For almost every other verb you form Konjunktiv II with würde + Infinitiv. That is not an emergency fix. It is the normal form in today's German:
- Ich würde mich freuen, wenn...
- Ich würde Sie bitten, ...
- Wir würden den Termin gern verschieben.
The old one-word forms of many strong verbs (hülfe, schwömme, träfe) sound old-fashioned in a letter. Leave them out. Nobody takes points off because you wrote würde helfen instead of hülfe.
But here is the line where I regularly see points lost when I mark:
With the six forms above, you don't use würde.
- ❌ Ich würde eine Frage haben. ✅ Ich hätte eine Frage.
- ❌ Es würde gut sein, wenn... ✅ Es wäre gut, wenn...
- ❌ Würden Sie mir das schicken können? ✅ Könnten Sie mir das schicken?
„würde sein“ and „würde haben“ are the classic B1 marker. They are not wrong in the sense of a grammar error, but they show the examiner straight away that the forms are not secure. This is the most expensive Konjunktiv mistake you can make, because it is so easy to avoid.
Konjunktiv II for the past: one form, a lot of impact
For the past there is only one construction, whether you mean Perfekt or Präteritum:
hätte / wäre + Partizip II (past participle)
- Ich hätte erwartet, dass die Lieferung pünktlich ankommt.
- Das wäre vermeidbar gewesen.
- Ich hätte mich über eine Information gefreut.
In a complaint, this construction is the strongest single building block you have. It says "you did something wrong" without saying it. It is polite and still unambiguous, and that double quality is exactly what Kriterium II is looking for.
If you take one sentence away from this whole article, make it this one: „Ich hätte erwartet, dass ...“ It fits almost every complaint, it is grammatically demanding, and you can learn it in thirty seconds.

Where Konjunktiv belongs in your letter
Not everywhere. A letter written in Konjunktiv from start to finish sounds indecisive, and your Leitpunkte (the task points) blur. Konjunktiv belongs in three places:
1. In the polite request, usually in the main part. Könnten Sie mir mitteilen, bis wann ... / Ich würde Sie bitten, ...
2. In the careful criticism or expectation. Ich hätte erwartet, dass ... / Das wäre so nicht nötig gewesen.
3. In the closing. Über eine baldige Rückmeldung würde ich mich freuen. / Ich wäre Ihnen sehr dankbar, wenn ...
Where it does not belong: in the facts. What happened, you write in the Indikativ. „Die Lieferung kam am 3. März an. Der Karton war beschädigt.“ Those are facts, not wishes. Put the facts in Konjunktiv too and you sound as if you are not sure they are true.
How this fits into the thirty minutes, and where the matching Redemittel (set phrases) are: the Knaxx Redemittel library, category 5.
The two-places rule
In the Knaxx Vier-Minuten-Check (four-minute check), the correction phase of the Knaxx Method, Konjunktiv is one of four fixed checkpoints. This is a Knaxx technique for your own checking, not a telc requirement: the official criteria do not prescribe any number of Konjunktiv forms, and the two places are our rule of thumb. The control question is:
Is there a Konjunktiv II in at least two places in my letter?
Two, not one. A single polite formula can be a memorised chunk, and that is how it reads. Two in different places show that you control the form.
Two is also the floor for peace of mind, not the ceiling for the text: three or four are perfectly fine if they land in the right places. Seven is too many.
The practical value of this rule is that you can check it in five seconds while the clock is running. You read the letter backwards, you count two places, done. The whole correction routine is in the Knaxx Method.
Five mistakes I keep seeing when I mark
1. „würde sein“ instead of „wäre“. In my experience, the most common one. See above.
2. Mixing up Konjunktiv I and II. „Er sagte, er habe keine Zeit“ is reported speech, Konjunktiv I. In the telc B2 letter you practically never need it. If you are unsure, avoid reported speech and write directly.
3. Konjunktiv in the wrong clause. „Wenn ich Zeit hätte, würde ich kommen“ is right. „Wenn ich Zeit hätte, wäre ich gekommen“ mixes present and past. Pick one time frame.
4. Politeness to the point of invisibility. „Vielleicht wäre es eventuell möglich, dass Sie unter Umständen ...“ The examiner is looking for a clear expectation in your closing. Politely worded, but clear. If you phrase yourself out of existence, you lose points in Kriterium I (Aufgabenbewältigung, task completion), because the Leitpunkt has not been covered.
5. Konjunktiv only in the closing. One single „Ich würde mich freuen“ formula at the very end, nothing else. That is the standard textbook solution, and it does not meet the two-places rule.
Twenty minutes of practice that actually change something
No grammar workbook. Two rounds on your own texts:
Round 1, ten minutes. Take a practice letter you have already written. Mark every request, every criticism and your closing sentence. Rewrite exactly those sentences, in Konjunktiv II. Nothing else.
Round 2, ten minutes. Take the six forms from the table. Write one sentence for each that could go into a real letter, not a drill sentence. „Könnten Sie mir mitteilen, ob der Kurs am Samstag stattfindet?“ is a sentence you will use. „Ich könnte einen Apfel essen“ is not.
Then clip both pages to your Redemittel list. On exam day you are no longer hunting for the form, it is already there.
Crack the Konjunktiv before it cracks your tone.
What Knaxx does differently here
A grammar course teaches you every Konjunktiv form. For the exam you need six, and you need to know where they should stand so that Kriterium II sees them. That is the difference between learning German and cracking the exam.

FAQ: Konjunktiv II in the telc B2
Do I really need Konjunktiv II for telc B2?
For a safe letter, yes. The official telc criteria do not mention it by name. Under Kriterium II, Kommunikative Gestaltung, they assess register and range of language, and Konjunktiv II is the clearest signal of both. In complaints, requests and refusals a letter without Konjunktiv II sounds curt, and the examiner takes that into account.
Which Konjunktiv II forms do I need to know?
Six are enough: wäre, hätte, könnte, müsste, sollte, dürfte. For every other verb you use würde + Infinitiv. On top of that, the past form hätte or wäre + Partizip II is worth learning, for example „Ich hätte erwartet, dass ...“.
Is „würde sein“ wrong?
Grammatically it is not strictly an error, but it counts as clumsy and reads like a B1 marker. With sein, haben and the modal verbs you use the real form: wäre instead of würde sein, hätte instead of würde haben, könnte instead of würde können.
How often should Konjunktiv II appear in my letter?
Our rule of thumb: in at least two places, at different points in the text. This is a Knaxx rule, not a telc rule; the official criteria name no minimum. A single closing formula is not enough, because it reads like a memorised chunk. Three or four are fine if they belong to the request, the criticism and the closing. The facts themselves stay in the Indikativ.
Do I need Konjunktiv I for telc B2?
Practically not. Konjunktiv I is used in reported speech and appears in journalistic texts, not in the letter you have to write. If you are unsure, phrase things directly and put your energy into Konjunktiv II.
Does Konjunktiv II also come up in the Sprachbausteine?
It can. The Sprachbausteine (the grammar and vocabulary section) test structures in context, and Konjunktiv forms are among the structures expected at B2 level. If you control the six forms, the same preparation earns you points there that you need for Schreiben anyway. More on this: Sprachbausteine B2, the logic behind the 20 gaps.
