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.
