Placing Yourself on the CEFR Scale, A1 to C1
The Common European Framework of Reference (CEFR) splits language ability into six levels: A1 and A2 for basic users, B1 and B2 for independent users, C1 and C2 for proficient users. At A1 a learner can introduce themselves and handle basic phrases. At A2 they manage simple routine exchanges such as shopping or describing their job. B1 covers talking about experiences and plans, and B2 is the level English-medium universities most often ask for.
Cambridge estimates roughly 90 to 100 hours of guided learning to reach A1, and around 180 to 200 hours in total for A2. Those figures help a learner set fair expectations. Twenty to thirty minutes of practice a day adds up to those hours slowly, and long gaps with no practice let them leak away again.
The Indonesian picture is worth reading honestly too. The 2024 EF English Proficiency Index ranked Indonesia 80th of 116 countries, in the low proficiency band, and in the 2025 edition its speaking score (447) came in below reading (491) and writing (479). Plenty of learners who follow written English comfortably still need more hours of talking. A placement test or a short practice test tells a learner which of the sections below deserves attention first.
