Lol for me, I wrote the DAT a total of 3 times. First time I wrote it, I scored a 22 on RC, 21 AA, 21 PAT. I wrote this during my third year of uni and wasn't too happy with my marks so I decided to rewrite it next year in November. When I rewrote it, I got a 17 on RC, 23 PAT, 21AA. That 17 on RC destroyed me and made me regret writing it so much because I didn't make the cutoff for Western. So this year, I wrote it again mainly so I would make the RC cutoff for western. Thankfully, I made the RC cutoff this year but honestly, if I could go back in time, I would stop myself from writing it a second time.
You can rewrite it to try and boost your PAT and AA but don't neglect RC, because a DAT score which may below average but you at least make the cutoff is better than not making the cutoff at all.
