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 Connectors: Weil, Obwohl, Trotzdem & Two-Part Formulas

German connectors belong to 3 grammatical families: Subordinating (verb at the end), Coordinating (Position 0), and Adverbial (Position 1 with verb-subject inversion).

Mathematical Formula Blueprints

Subordinating Connector (Subjunktor)

Words like weil, obwohl, dass, wenn kick the conjugated verb to the end.

Hauptsatz+, obwohl / weil+Subject+Mittelfeld+VERB AM ENDE

Example:

"Er ging zur Arbeit, obwohl er Fieber hatte."

Connector: obwohl | Verb am Ende: hatte

Adverbial Connector (Konjunktionaladverb)

Words like trotzdem, deshalb, außerdem occupy Position 1 and invert subject/verb.

Satz 1+. Trotzdem / Deshalb (Pos 1)+VERB (Pos 2)+Subject (Pos 3)

Example:

"Er hatte hohes Fieber. Trotzdem ging er zur Arbeit."

Position 1: Trotzdem | Verb (Pos 2): ging | Subject: er

Core Rules & Sentence Mechanics

Position 0 Connectors (ADUSO: aber, denn, und, sondern, oder)

Coordinating conjunctions do not count as a position. The sentence continues with standard Position 1 (Subject) + Position 2 (Verb).

Er lernt viel, denn (0) er (1) will (2) die Prüfung bestehen.

Two-Part Connectors (Zweiteilige Konnektoren)

Paired conjunctions connect two parallel concepts: nicht nur ... sondern auch (addition), weder ... noch (double negative), sowohl ... als auch (inclusive).

Er spricht nicht nur fließend Deutsch, sondern auch perfekt Englisch.

Connector Classification & Word Order Matrix
Connector Group	Key Words	Position	Verb Placement
Coordinating (ADUSO)	und, aber, denn, oder, sondern	Position 0	Position 2 (Standard S-V-O)
Subordinating (Subjunktoren)	weil, obwohl, dass, wenn, als, da	Clause Start	Absolute End of Clause
Adverbial (Konjunktionaladverbien)	deshalb, trotzdem, sonst, außerdem	Position 1	Position 2 (Inverts: V-S)
Two-Part (Additive)	nicht nur ... sondern auch	Split	Depends on clause structure
Two-Part (Alternative)	entweder ... oder	Split	Standard verb order in both
Two-Part (Negative)	weder ... noch	Split	No extra "nicht" needed

Official Goethe & telc Exam Traps

The "Obwohl" vs. "Trotzdem" Confusion

Both mean "although / nevertheless", but obwohl creates a subordinate clause (verb at end) while trotzdem is an adverb in Position 1 (verb in Position 2).

COMMON MISTAKE (0 Points)

Er kam pünktlich, trotzdem es regnete. (WRONG)

CORRECT STRUCTURE

Er kam pünktlich, obwohl es regnete. (CORRECT)

Examiner Rule: Use obwohl inside a single comma-separated sentence. Use trotzdem to start a new clause with verb in Pos 2.
