When timed practice puts you comfortably above 55% overall, with no component anywhere near the 25% floor, and does so repeatedly rather than once. Feeling ready is not evidence. A run of scored results under real time pressure is, and it is the only thing that makes booking a decision instead of a gamble.
Short, frequent practice with immediate feedback. Answer a few exam-style questions, see what you got wrong, read the correction, repeat. Five minutes a day beats a three-hour session the week before, because reading improves with reps rather than with theory.
Faster than almost anyone. Portuguese and Spanish share roughly 89% lexical similarity and closely parallel grammar, so a Spanish speaker can often reach A2 in 80 to 120 hours of focused study. Some report being exam-ready after 2 to 3 months of casual study.
Most learners need between 150 and 350 hours of study to reach A2 from zero. That is roughly 3 to 12 months, depending on how many hours a week you can commit and what advantages you bring. A Spanish speaker may need 80 to 120 hours. A speaker of a non-European language may need 300 to 400.
Five to ten hours a week suits most working adults and reaches A2 in roughly 4 to 8 months. More than 15 hours a week is faster but rarely sustainable alongside a job. Below 3 hours a week works but slowly, because you lose time to relearning between sessions.
Not conceptually. A2 is the elementary level: introducing yourself, simple transactions, short everyday texts, basic messages. Most adults reach it with consistent study over months. The genuinely hard parts are European Portuguese pronunciation for listening, and sustaining a routine long enough to get there.
Switch your listening input to European Portuguese immediately, because ear training is the slowest thing to fix and listening is 30% of the grade. Then move your reading material across and relearn the everyday vocabulary that differs. Practise only on European-Portuguese exam material.
Everyday European Portuguese, not academic language. Transport, shops, food, health, housing, work, family and daily routine. The texts are signs, messages, notices and short personal stories, so the useful vocabulary is what you would meet living an ordinary week in Portugal.
