Hello everybody,
As some of you may have noticed, LingoDeer now has a new “BOOSTER” tab (on Android, with iOS not far behind) for Korean, Japanese, Chinese, French, Spanish, and German. This section includes a variety of exercises so you can practice and challenge yourself in your target language.
What’s included in BOOSTER:
Vocabulary drills
Use diverse practice modes (e.g., Listening, Spelling, Word Match, Comprehensive, etc.) to boost your vocabulary.
Collocation drills
Practice all the useful phrases, collocations, and common patterns that will help you make steady progress.
Grammar drills
Test your knowledge of practical grammar, with clear mistake explanations written by our language instructors.
Comprehension drills
Check your understanding of written and spoken language... with no translations! (*this is a really fun one, go check it out!)

P.S. Fluent section (now called "Fluency Builder") and Travel Phrasebook have been moved to the BOOSTER tab.
