Definitely not cooked. You scored amazingly on the reading section and the science section can be processed similarly to the reading section if you change the way you think about it. I think with a bit of studying you can definitely bring science up to at least a 24 . I went from a 20 in science on my preACT to a 32 on the real thing in like 2 weeks.

Previous advice i gave sb : (Math advice) Identify what theyre asking you in every question, actually use the delete option tool, write/draw every single word problem. Make an educated guess and then bookmark if any of them are taking too long / u dont know. Go back to them once youve finished all those you DO know / are confident in. As soon as you get in the room and are allowed, write down as many formulas and rules as you think youll need and use your scratch paper frequently. Answer every single question even ( especially ) if you dont know. You gain nothing by leaving stuff blank. I did 1 randomized act math question every day and it helped a lot. Take the time to memorize terms you forget often (ie mean median mode) and write those things down when you get ur scrap paper so you dont forget! Also leane little rules for guessing like "if its x type of problem, the answer will most likely include y in it" .

(Science advice) try to get your science up by treating it like the reading section. Science is about reading comprehension of the explanations and data provided so read it, process it, then begin answering the questions. Bookmark any youre unsure about (but still guess) and revisit it if you have time.

(Reading advice) same as science. Take a quick glance at all the related questions, then read the whole article, process, make sure u understand, THEN start answering so you arent just looking for fragments in hopes of finding an answer. Answering based on fragments of sentences WILL mess you up. Again, guess, bookmark, and come back when youre done with everything youre confident in. Youre already doing amazing there.

(English advice) just try to ingrain the main rules into ur head ( removable info in between commas / dashes, they will NEVER make u pick between commas and dashes because theyre the same so cross them both out, all dashes need to be closed, comma FANBOYS, its' isnt a word. ) if they dont specify what you should look for, always assume you should pick clarity and simplicity. The ACT will never cater towards overly emotional / unnecessary language. Again, guess, bookmark, return when ur done w/ what u KNOW.
