Exactly HOW important is continued education after a bachelors?

I haven't taken classes in two years, took one last semester, and am not taking anything this semester because I want to study for the DAT instead. Is this a bad idea?! I took the DAT in 2015 and got an 18... I definitely need to improve. I've forgotten a lot of material so I will be relearning a lot to master the material to do well. I will also be working full time and helping out at a local dental assisting school on Saturdays. I wont "just" be studying, but I won't be in school.
