AstroWord Learn teaches Vedic astrology (Jyotish) from zero. Each lesson is a short set of questions - pick the answer, match pairs, put things in order - with a streak and XP to keep you coming back. Every lesson ends with a question about your own birth chart, so you learn by reading the chart that is actually yours.
The lessons follow the classical Parashari system with whole-sign houses and the Lahiri ayanamsa - the same rules AstroWord uses to calculate your chart and reports.
