How is Nail German different from apps like Duolingo or Babbel?

Duolingo and Babbel focus on general casual vocabulary matching. Nail German is an intensive examination drill engine built specifically for the grammar sections of official Goethe-Zertifikat and telc exams. It enforces strict CEFR rules, timed 15-minute mock simulations, and Leitner 3-streak active recall.

Which specific exams and CEFR levels are supported?

The curriculum spans all 6 CEFR levels (A1, A2, B1, B2, C1, C2) calibrated for Goethe-Zertifikat (A1–C2), telc Deutsch (A1–C1 Hochschule), and TestDaF.

Why is the Exam Simulator passing score set to exactly 60%?

Both Goethe-Institut and telc gGmbH officially require a minimum score of 60% (60/100 points or 9/15 items) to award an official language certificate. We match this exact Bestehensgrenze in our 15-minute exam simulator so you know your true test readiness.

Is the €19.99 Lifetime Pass truly a one-time payment with no subscription?

Yes. You pay €19.99 once and unlock permanent lifetime access to all 1,647 verified questions, all 6 CEFR levels (A1 to C2), unlimited exam simulations, and all future question updates with zero recurring charges or hidden fees.

Can I install this on my iPhone, Android, or laptop offline?

Yes! Nail German is built as a Progressive Web App (PWA). Open app.nailgerman.com on Safari or Chrome, tap Add to Home Screen, and the app installs as a full-screen standalone application that saves your local progress and works offline.

How does the 3-Box Ampel Leitner system work?

Every question is tracked individually in local storage. Missed questions drop to Box 1 (Rot) for immediate re-drilling. Questions advance to Box 2 (Gelb) upon 1 correct hit, and are only stamped Box 3 (Grün • Mastered) once you achieve 3 consecutive correct hits across mixed interval drills.

Should I use Nail German alone or alongside my current German course?

Nail German is engineered as the ultimate high-yield examination companion. While structured classroom courses (VHS, Goethe-Institut) and conversation apps provide listening and immersion, Nail German provides the high-frequency active recall drills needed to master examination grammar and clear the strict 60% Bestehensgrenze under timed pressure.

German Sentence Structure & Word Order Rules

German word order follows strict mathematical placement. In standard main clauses, the conjugated verb is locked in Position 2. In subordinate clauses (weil, dass, obwohl), the verb moves to the absolute end.

Mathematical Formula Blueprints

Main Clause (Hauptsatz)

The conjugated verb is locked in Position 2. Non-verb elements move around it.

Position 1 (Subject / Time / Object)+VERB (Position 2)+Mittelfeld (TeKaMoLo)+Partizip II / Infinitiv (Ende)

Example:

"Gestern habe ich mit dem Zug nach Berlin gefahren."

Position 1: Gestern | Verb: habe | Verb Ende: gefahren

Subordinate Clause (Nebensatz)

Subordinating connectors (weil, dass, wenn, obwohl) kick the conjugated verb to the end.

Connector (weil / dass)+Subject+Mittelfeld+CONJUGATED VERB (Ende)

Example:

"Ich lerne jeden Tag Deutsch, weil ich in Deutschland studieren möchte."

Connector: weil | Subject: ich | Verb am Ende: möchte

Core Rules & Sentence Mechanics

The Inversion Rule (Inversion bei Vorfeld-Besetzung)

If you begin a sentence with time, place, or an object (Position 1), the subject immediately swaps places with the verb and moves to Position 3. The verb stays strictly in Position 2.

Heute (1) gehe (2) ich (3) ins Kino. (NOT: Heute ich gehe ins Kino)

The TeKaMoLo Rule (Mittelfeld Sequencing)

When multiple adverbial phrases appear in the middle field, they strictly follow: Temporal (When?) -> Kausal (Why?) -> Modal (How?) -> Lokal (Where?).

Ich fahre jeden Morgen (Te) wegen der Arbeit (Ka) mit dem Bus (Mo) nach München (Lo).

Official Goethe & telc Exam Traps

The "Weil" vs. "Denn" vs. "Deshalb" Word Order Trap

All three words mean "because" or "therefore", but each requires a completely different verb position in Goethe and telc exams.

COMMON MISTAKE (0 Points)

Ich bleibe zu Hause, weil ich bin krank. (WRONG)

CORRECT STRUCTURE

Ich bleibe zu Hause, weil ich krank bin. (CORRECT)

Examiner Rule: weil = Verb at End | denn = Position 0 (Verb in Pos 2) | deshalb = Position 1 (Verb in Pos 2, Subject in Pos 3)
