conflict of schedule

hii poo, so i applied for a job po and fortunately naka-pasok naman butt PST training pa lang, problem ko po is that during the second last day of the training is enrollment day ko po and since strict sa attendance— idk if sasabihin ko sa trainer namin or lost a timing sa program na gusto ko since paubusan ng slots huhu

any advice po? T^T ❤️
