Slang offers an unprecedented variety of comprehensive, career-specific English courses. Our adaptive English learning app optimizes your learning experience in real time, getting to know you as a learner and presenting you with the study experience you need based on how where you are in your English-learning journey. Other solutions all follow the same one-size-fits-all approach, teaching only the highest-frequency terms, covering less than 1% of the English language and leaving out the field-specific knowledge you need to be a bilingual professional. Slang is here to help you go beyond basic English and unlock your potential by making English-language knowledge around the world accessible to you. If you’re a new user, you’ll receive a free 7-day trial to Slang Pro and get a chance to explore the comprehensive selection of professional English courses we offer. After your trial, subscribe to Slang Pro for unlimited access to all Slang courses and features. THE SLANG APPROACH Study only what you don’t know: stop wasting time on one-size-fits-all solutions. Slang builds a personalized learning experience so that you study only what’s new for you. • We make things easy: translations and explanations in your native language support you while you build toward total immersion. • Reach fluency quickly: our adaptive technology measures your proficiency in real time and selects the study material and activities that will help you progress faster. • A lifelong learning companion: your knowledge syncs across all of our English courses, so you can easily study new topics without repeating content. • A comprehensive solution: our wide variety of exercises helps you master all four language skills — reading, writing, listening, and speaking.
