If you register close to the deadline, ESAT spaces may be limited. ESAT is relatively new, and with high demand, testing centers may have limited availability, especially for popular dates and locations. To secure a spot, check the registration portal as soon as possible to see what dates are still open. If the closest centers are fully booked, you might still find availability at other locations nearby. It’s also a good idea to sign up for notifications if the registration site offers it, in case more slots become available due to cancellations.
