You’ll usually need at least an intermediate level of English (B1) to join an IELTS course. Some centres will take you at that level, but honestly, you’ll get a lot more value if you’re closer to upper-intermediate (B2). That way, you’re not stuck learning basic English and can actually focus on cracking the test.
If you’re around B1, you can still join, but expect a mix of test prep and general English improvement. Once you’re at B2, you’re in a much better position to work on strategies and push your score into the 5.5 to 6.5+ range.
And if you’re already at an advanced level (C1 or C2), then you’re aiming higher, usually for top university entry or professional registration, where strong scores really matter.
So, in simple terms:
B1 gets you in the door, B2 helps you make real progress, and C1 is where you start chasing the big goals.
