I'm also pretty nervous-- taking it for the first time next Tuesday! So [INSERT DISCLAIMER] while I have no "proven"/experienced test-taker advice for ya, I am right there with you! That being said, I do second what others have said about the importance of relaxing/"anti-burnout" activities in your schedule too (exercise, video games, music, breathing fresh air outside, etc)...I've found that I sometimes study myself into a slump without even realizing it, until I take even one day off. I'm sure that's NOT the advice anyone who takes studying seriously wants to hear (myself included), especially this close to the big exam date, but it's definitely got some mental health benefits that will probably help to keep one positive/confident during this week of mounting dread. Of course, moderation is key. End rant. If you've hit your target score even once/know it is a possibility, I'd say go for it!
