Booking your IELTS exam date 2024 slot as early as possible is highly recommended. IELTS test dates can fill up quickly, particularly in major cities or during busy months. Ideally, you should aim to book your slot at least 2-3 months in advance to ensure you get a convenient date and location. This gives you enough time to prepare thoroughly without the stress of last-minute arrangements. Be sure to check the British Council or IDP websites for the latest test dates and register as soon as you feel ready.
