Choosing the wrong English exam is an expensive mistake. Not because the exams are wildly different in difficulty — but because the wrong exam score simply won't be accepted by your university, visa authority, or professional registration body. You'll have wasted months of preparation and hundreds of dollars on a certificate that doesn't open the door you need.

B2 is the most important English level for most people on the planet. It's the level most employers mean when they write "fluent English required." It's the minimum for most UK and European university programmes. It's the gateway to most skilled worker visa pathways. And it's the threshold where using English stops feeling like a performance and starts feeling like a tool.

Not all English certificates are created equal. Some are accepted by immigration authorities on five continents. Some are required by specific professional bodies. Some are useful for your CV but carry little weight in formal applications. And some — the ones that matter most — can only be taken online, on your schedule, without sitting in an exam centre.
