Most "best of" lists rank sites by traffic, not by what they actually help you do. Here's a more useful way to choose: what job are you trying to get done, and which tool is actually built for it.
IELTS practice websites fall into a few genuinely different categories, and the right one depends on which skill you're working on — not which site has the biggest homepage. Reading and Listening have fixed correct answers, so any well-built free test works. Writing and Speaking don't have a fixed answer, which is exactly where most "free" sites quietly stop being useful.
This is where free sites genuinely shine, because there's a real answer key behind every question. Large free practice libraries with hundreds of tests exist specifically for this — they're a legitimate way to build timing and familiarity with question types at no cost. Official British Council and IDP sample tests are also free and are the most exam-accurate for format, since they're written by the actual test providers.
A free site can hand you a Task 2 prompt and a timer. What it usually can't give you is an honest answer to "is this a 6.0 or a 7.5" — because that requires scoring against the actual IELTS criteria, which takes either a trained human or a properly-built AI model, not a generic grammar checker. Some larger free-test sites do offer human-scored Writing feedback as a paid add-on, typically with turnaround measured in days (commonly around 48 hours) rather than instantly — a reasonable option if you're not in a hurry. If you want to know where you stand today rather than in two days, that's a different tool for a different job — AI feedback built specifically against the real band descriptors, delivered in under a minute, is what IELTS Master is built for.
Global paid IELTS courses are a legitimate option, but they're priced abroad — commonly somewhere in the USD $50 to $250 range depending on the platform and plan length — and billed in a foreign currency regardless of where you live. If cost and currency are real constraints, that's worth weighing against a locally-priced, one-time-payment option before committing to a recurring or high-upfront foreign course.
A separate category of free sites focuses on Speaking cue cards and topic vocabulary lists, organized by theme. These are genuinely useful for building content ideas before you speak — but they don't score your actual delivery, so pair them with something that gives you real feedback on fluency, grammar range, and pronunciation rather than relying on the cue card alone.
