<p>When do you plan on taking it again? Just out of curiosity, because some of the tips I have may take a couple months. But anyway…
The first thing I note about this is your determination. I’m just going to start right off and say that I think you absolutely can raise your score.
English–Make sure you know the grammar rules. I know it sounds basic, but I haven’t taken English Grammar since 8th grade, so I did a bit of review just to make sure I knew everything, i.e. the noun modifying verbs, pronouns, colons/semicolons, etc. Also, remember that usually the best form of writing involves packing as much punch in as few words as possible. The ACT loves having shorter answers. Don’t be wordy or over-think it. The simpler the better, as long as it makes sense. (I know the grammar rules thing seems a bit obvious and elementary, but I ended up with a 35 in this section, and only because I knew the rules. I definitely recommend doing that, even if you think you already know them.)
Math–oh my goodness. I ended up with a 24 too, because I took my own sweet time and then was only halfway through with 10 minutes left. I don’t know if that’s your problem, because personally I really need to work on that. If it’s just the concepts, use the Real ACT book if you’re not already. They have this really cool scoring thing that shows which questions you got wrong were from which sub-section (algebra, plane geometry, etc). I use Khan Academy as a good source for reviewing material. A lot of people seem to have problem with the trig section, which is actually my best part. So if you have any questions, don’t hesitate to message me. Or, I mean, anything. Where I live there’s 2 feet of snow and negative temperatures, and school is canceled for the rest of the week. I’m doing nothing, haha 
Reading–I may not be the most help for this, because I enjoy reading (and this section…I’ll go hide in my corner). In all seriousness, you should read a lot. Like, Wall Street Journal and your parent’s old college textbooks and classic books. The stuff on here is college-level, so you want to get used to comprehending it. Also, learn to speed-read. With good comprehension, of course. But there are lots of tests online that will tell you your current speed, and help you to get to a higher rate. Last month I was at 700 wpm with 75% comprehension. With a bit of practice, I rose to 1000 wpm with 90% comp. When you’ve got so little time, every little bit counts. (I truly don’t know if you read fast or not, but I’m a nerd and read so. freaking. much. so don’t feel down on yourself if you’re at like 300 wpm or whatever. ) When you read the paragraph, make sure you not the tone–is it friendly, casual, formal? Is the narrator scared, hopeful, unsure? What’s the main idea? What is the narrator telling you, what is the big idea information in the social studies, etc. sections? The last thing–this will sound weird–but pretend to enjoy the passages. I don’t mind the section as a whole, but I usually hate a couple of the passages. So what I do is I tell myself “I’m so interested in this passage about the intricate mating calls of sloths, hrm, hrm, indeed, quite.” Just try to get yourself in the mindset of really being interested in what the passage has to say because hey, sometimes it is interesting! If you enjoy it, you’ll retain the material faster, even if you have to trick yourself into it. I know this sounds super strange, but I got a 34 so it worked for me…can’t hurt to try!
Science–basically people either love this section or hate it. You have to be fast, though. Be sure that you’re not reading the graphs/experiments but just skipping to the questions. I didn’t need to read them at all, but just look at the questions and find the corresponding charts. Also, point your finger at the charts and graphs and everything. It avoids stupid mistakes and helps focus you. For the scientists’ opinions, you’re obviously going to need to read it. What I do is skim, underline what may be important, and get the main idea of what the scientist is saying. Then I’ll answer the questions and refer to the paragraphs as needed. Remember everything you need is right in front of you. Same with the reading section.
Also, one VERY IMPORTANT tip that saves a lot of time–don’t bubble in every question after you answer it! It saves a lot of time to not do that. I was unsure at first, but then I tried it, and it works. Instead, circle the answers and bubble them in later. So for English and Math, do the left/right pages, circle the answer in the test booklet, and bubble them in after the two pages. For reading/science, do it after every passage. That way, you don’t lose focus, either!
I hope this helps! By the way, I hope I don’t come off as condescending or arrogant. Sometimes my friends say I do, and I don’t mean to at all, but with Asperger’s I don’t really notice if I come off as rude. I really do want to help, so I hope I don’t seem like that! Also, feel absolutely free to message me with any questions, or just reply to this if you ever have any. I quite enjoy it, and it helps me to study too! Don’t be shy! :)</p>
