About this bundle

FlashBoss is a study tool in RPG armor. Words arrive in clusters of about two dozen, spaced repetition brings each one back as it starts to fade, and a boss fight at the end of every cluster refuses to let you past until its hardest words are yours. Spanish Core carries tiers 1–5; Pareto 1 and Pareto 2 add tiers 6–15 — 3,000 words in all, each with an example sentence, text-to-speech audio, and its translations and study notes in English, German, Japanese, Russian and Simplified Chinese. Every lesson is readable in those languages too. Already own FlashBoss or one of the packs? Complete the Set charges you only for what you are missing.
