Am I B1 or B2 in English?
The honest answer: you probably can't tell for sure on your own — and you most likely lean toward overestimating. The B1/B2 line is the single most-confused boundary in English learning, because both levels let you "have a conversation," which is the thing people use to judge themselves. The difference is in how much you can do without strain.
Short version: B1 means you can handle familiar situations and get your point across, but you simplify, hesitate, and lose the thread in fast or abstract conversation. B2 means you operate independently — you can follow a native-speed discussion, argue a point, and read most things without a dictionary. If you're often translating in your head or avoiding tenses you're unsure of, you're likely still B1.
B1 vs B2 in English: the real difference
B1 (Intermediate) — Can deal with most situations while travelling. Can describe experiences, give brief reasons and opinions. Reads straightforward texts for gist. Conversation works on familiar topics but breaks down when it speeds up or turns abstract.
B2 (Upper-Intermediate) — Can interact with native speakers fluently and spontaneously across a wide range of topics. Can produce clear, detailed, argued text. Can follow most TV, films, and meetings. Understands implicit meaning, not just the literal words. This is the "independent user" threshold employers and universities care about.
The clean test: at B1 you survive a conversation; at B2 you can actually hold your own in one — including disagreeing, joking, and handling a topic you didn't prepare for.
Signs you're still B1 (not B2 yet)
You translate in your head before speaking, especially under pressure.
You stick to simple tenses and avoid the ones you're unsure of (perfect aspect, conditionals, passive).
Fast or accented native speech loses you, and you ask people to repeat or slow down.
You can read a simple article but a news opinion piece or a contract is heavy going.
You can give an opinion, but defending it with nuance ("it depends on…") is a struggle.
Signs you've crossed into B2
You follow a group conversation at natural speed without everyone slowing down for you.
You catch jokes, sarcasm, and what people imply but don't say.
You can write a structured argument — intro, points, counterpoint, conclusion — without it feeling like a wall.
You read most things (news, work emails, articles) without reaching for a dictionary every line.
You repair your own mistakes mid-sentence instead of freezing.
Why do so many people guess wrong?
Because self-assessment is unreliable and biased upward. The usual pattern: someone holds a basic conversation on holiday, feels confident, and assumes B2 — then takes a real exam (or an interview) and lands at B1. Confidence isn't the same as range, and "I can communicate" hides a wide gap between B1 and B2.
The CEFR descriptors are specific and measurable for exactly this reason. The only way to remove the guesswork is to measure against them rather than against your own feeling.
How to know for sure
Take a CEFR-aligned test instead of guessing. Nivelo's free 5-minute test adapts to your answers and places you in a range (like "B1–B2") immediately — no signup required to start. If you're right on the line, the 30-minute test pinpoints a single level and shows which skills are holding you back.
Knowing the real answer matters: targeting B2 prep when you're actually B1 wastes weeks, and assuming you're B2 before an exam is how people lose the exam fee.
