Просто читаешь и понимаешь, как устроен язык — без зубрёжки и сухих правил. Grami — гайдбук по грамматике на русском: английский, немецкий, французский, испанский, португальский, греческий. От полного нуля до уровня B2. ЧТО ВНУТРИ • Грамматика по уровням A0–B2 — читай в любом порядке, с нуля или с того места, где остановился • Объяснения на русском, без академической скуки • Живые примеры из реальной жизни: кафе, банк, работа, врач, аэропорт • Озвучка в каждой статье — сразу слышишь, как это звучит • Личный словарь — сохраняй слова прямо из статьи и тренируй их по месяцам • Упражнения после каждой темы: перевод, выбор варианта, пропуски • Fast-Track — только ключевые темы, если нужно быстро ЯЗЫКИ • Английский — времена, артикли, пассив, условные предложения • Немецкий — падежи, порядок слов, глаголы с отделяемыми приставками • Французский — алфавит, артикли, пассив, склонения • Испанский — времена, subjuntivo, ser и estar • Португальский — европейский вариант • Греческий — алфавит, артикли, склонения КАК ЭТО РАБОТАЕТ Выбираешь язык и уровень. Читаешь тему, слушаешь озвучку, разбираешь примеры, закрепляешь упражнением. Новые слова уходят в личный словарь — вернёшься к ним, когда будет удобно. ДЛЯ КОГО • Учишь язык сам и хочешь понимать правила, а не зубрить фразы • Понимаешь на слух, но путаешься в грамматике • Начинаешь с нуля и не знаешь, за что взяться • Готовишься к переезду, работе или учёбе за границей ОПЛАТА Разовая оплата за гайдбук — без подписки и скрытых платежей. Первые темы бесплатно. Никаких стриков, напоминаний и геймификации. Просто хороший учебник — всегда под рукой.

Afraid to blow your first deposit? Here it costs nothing: $10,000 in virtual money, a live chart and a review after every answer — where the zone was and why the price went there. WHAT'S INSIDE • 119 lessons from simple to advanced: candles, market structure, levels, Wyckoff, Smart Money • A library of 96 articles and 221 terms, always open when you forget something • A simulator on live quotes: a virtual account, no real money • A trading journal and a review of your own decisions • A test after every level • Five languages in the app: English, Russian, Kazakh, Ukrainian, Uzbek HOW IT WORKS Every exercise is two charts and one question. You choose, the app shows the breakdown. The correct answer is computed in advance on historical data, not made up on the fly. The app remembers where you go wrong most often and brings those topics back. After a week you see not an overall percentage but a specific weak spot. WHY HERE Most learning apps stop at chart patterns and indicators. Here the course goes on to market structure, liquidity and Smart Money, built on the Wyckoff method that dates back to the 1930s. The author has been trading since 2019 and teaches the same system used in the author's own trading. WHAT'S NOT HERE This is an educational app. There is no real money, no brokerage accounts, no order execution and no trading signals. The simulator account is virtual; its results are not returns and promise nothing. Trading financial markets carries a risk of losing money. The app teaches chart analysis and is not investment advice. SUBSCRIPTION Pro and Pro+ are auto-renewable subscriptions for a month or a year. Payment is charged to your Apple ID when you confirm the purchase. The subscription renews automatically unless cancelled at least 24 hours before the end of the period. You can manage and cancel it in your Apple ID settings. Terms of Use: https://extremum.kz/terms.html Privacy Policy: https://extremum.kz/privacy.html
