Update: I actually got a 36
https://www.reddit.com/r/ACT/comments/1sbpdv0/im_actually_in_shock_rn_score_jump/
So if anyone saw this post, I have some news. Apparently, in my state (Alabama), district testing scores were revoked for about a week due to a discovered issue. They told everyone that our scores would come back the same or possibly higher. I figured that this meant nothing, that one school messed up the way that they sent in tests or something, and nothing would change. Today, with no email or other indication that my scores might be released, I checked the ACT website, used my ACT score hider from right to left, saw that my English was the same, and then.. I revealed math, saw that it was a 36, and knew that it meant my composite must be a 36, but I still didn't believe it until I clicked on it, and it was just right there. All my hard work finally paid off. So I've done it. I finally doubled my score from an 18 to a 36.
Thank you to everyone who has supported me on this journey!!
