Should I quit my dental assistant course?

I think this is too simple of a question, without details. If you are more than 50% through, then definitely do NOT quit...

In fact, I would say don't quit at all unless you've got something else lined up to improve future job skills.

In this job market, starting a job skill course and not finishing it would be pretty silly, unless you can come up with a logical reason why you could never be hired for the job you are training for.

Yes. It isn't that "simple" of a job, and you said that it is what you wanted.

I’m not letting you put your grubby hands in my mouth 😂
