Which category do I fall into for registering my TM-30 if I arrived visa exempt in Thailand?

The user is seeking clarification on the category to register their TM-30 form, as they arrived in Thailand visa exempt, which allows for a 45-day stay as a UK citizen. The community suggests categorizing as 'Ex 30' since the extended 45-day exemption is temporary, linking it to the standard 30-day visa exemption. There are also inquiries about the education visa category.
