Courses
Every course is a path from zero to confident command: a skill graph on its own level scale, and word memory on top of that for language courses. Not a playlist of lessons.
English
A0 — C2From “how much does this cost” to interviews and negotiations: grammar, vocabulary, pronunciation, writing.
Chinese
A0 — C2Mandarin from scratch: tones and pinyin, character recognition, measure words and word order. Every example comes with pinyin, so no handwriting is needed.
Turkish
A0 — C2Vowel harmony and suffixes instead of prepositions — an unfamiliar logic from the first lesson. For people heading to Turkey, working with Turkish business, or getting ready to relocate.
Russian
A0 — C2Cases, verb aspect, word order — the things everyone learning Russian trips over.
Uzbek
A0 — C2Latin script as the base, Cyrillic optional. For people who have moved there or work with Uzbekistan.
Java
ZERO — ARCHITECTFrom your first program to architectural decisions: the language, the JVM, garbage collection, concurrency, security and system design. Current for Java 25 LTS and Java 26.
