Totally disagree. Going to grad school is a pretty big commitment. I think a lot of people who go to grad school go because they have been in school their whole lives and don’t know how to do anything other than being a student. Yeah, you may never go back, but that’s probably a good thing - it means you weren’t really committed to whatever career you thought you wanted. Trust me, I’m going to grad school this year, eight years after I got my BA. If you really want to do it, you’ll do it.
Practice tests, practice tests, practice tests, practice tests. Until you’re consistently getting scores you’re happy with.
