What can I do if I can’t keep up with online exams?

Hi everyone, I’ve been falling behind in my classes and now my online exams are around the corner. With work and everything else going on, it feels impossible to prepare. Honestly, i need someone to do my online exam because I don’t want to fail. Has anyone here tried getting help with this before? What’s the safest way to do it without getting into trouble? I’d really appreciate your advice.
