A game for practising Spanish individual and collective nouns (sustantivos individuales y colectivos), aimed at Year 13 students (2.º de Bachillerato) preparing for the PAU university entrance exam. It has four modes. Memory cards pair each individual noun with its collective (oveja and rebaño, pino and pinar) across three timed levels, and each correct pair shows the definition, the type of collective (lexical, or derived with a suffix) and an exam tip. Quick practice gives you one minute to classify words or find the collective for each individual noun. The PAU simulator has multiple-choice questions grouped by Spanish region, marks them with the exam rule of +1 per correct answer and −0.33 per wrong one, and explains each answer following the RAE and its grammar (NGLE); AI can also write new batches of questions. The glossary lists 41 pairs, filtered by category and word formation. The interface is in Galician, and it works on mobile.
