Maybe contacting the school to ask if the programme is going ahead could shed some light on why? I wouldn't be surprised if applications have been temporarily suspended, maybe until next spring or so. Hungary is now subject to a travel ban, so travelling to Budapest for an assessment won't really be a possibility in the immediate future. In addition, Wizz air have just announced capacity reductions for the winter. Crews in some bases will be facing unpaid leave or part-time work for certain periods in the next 6 months. So, unfortunately, it's quite possible that ab-initio courses in the next couple of months have been postponed as well. But, as I previously said, you need to contact whoever is managing it to know for certain what's going on.
