Getting absolutely cooked by scheduling

Last time my ssb I couldn't attend cause school pracs ...wrote to both ssb and school to get either postponed but it didn't work.....now again nda ssb is clashing with offline verification at college and they are refusing to give any leeway 😭 final straw would be just TES tf should I do....with so many people there screening in would be super hard as opposed to NDA where it is hard but with fewer people

Idek if NDA will consider my postponement request

Just a rant mostly
