Step 1: register an account on the official CTI website, using your name exactly as on your passport, plus nationality and ID details. Any mismatch can invalidate your score for applications.
Step 2: choose your level and a nearby test center, check the deadline and exam date, upload a compliant recent photo (white background, no hat), and fill in your contact details.
Step 3: pay online — only payment completes registration. For rescheduling or refunds, act before the deadline per center rules. About a week before the exam, print your admission ticket, verify the venue, and plan your route.
