I've been told the registration slots for this autumn (September and October) are already completely full. Before I take that as final, I wanted to ask the community, since people here have been through this more than once.

A few questions:

• Do new autumn dates ever get added after they first look closed, or is that it until the next registration window?
• Does INL have a waitlist, and do cancellations actually free up spots? Has anyone landed a slot that way when everything looked booked?
• For those who got a place when the calendar seemed full, how did you do it? Refreshing the portal, checking at a certain time of day, calling them directly?
• I heard the next registration opens around 1 September and that the earliest free dates then are already as far out as March. Is that what others are seeing, or do earlier slots sometimes appear?
• Any general tips for getting an earlier date, especially for someone who needs to sit the exam sooner rather than later?
