Retaking a “Decent” DAT Score — How Do I Push Into 24+? (Repost w/ Details)

EDIT: For some reason only the title posted earlier and none of the details showed up.

I took the DAT about 2 years ago and scored TS 440 (21), Bio 500 (25), PAT 450 (21). I’m planning to retake it and used Bootcamp the first time. For those who improved from similar scores, what did you change or use differently? I know my original score isn’t low, but I need a 24+ (23 minimum), so I’m looking for advice geared toward breaking into that range.
