<p>Which prep guide, if any, should I get?</p>
<p>Bump.</p>
<p>Also another question:
How to make sure I don’t run out of time? I took my first ACT practice (an actual one) test and got 30 Composite (which is terrible compared to my 2100 SAT). I ran out of time on Reading (no time to do the last passage) and Science (no time to do the differing viewpoints section).</p>
<p>the REAL ACT.</p>
<p>Reading, I always have a heard time with this section. What I do is read the passage really fast then answer the questions. I don’t think it really worked so well for me, by the time I was on the last passage I had 3 minutes left (still finished).
Science, I skimmed through the passages really fast and underline key words to understand what I am looking at. Then I look at the graphs for about 5 seconds then start on the questions. This helped me a lot and I finished the science section with 3 minutes remaining to check answers. 
I get my score on the 28th and I hope I did well.</p>
<p>^Agreed, get the Real ACT. Also, Princeton Review will help you nail the English and Math section. For Reading/Science, the time constraints are usually a problem for everyone. What you need to do is practice taking those sections under even SHORTER amounts of time- start with the usual 35 minutes, then make it 30, and so on and so forth. Doing this will make testing conditions more comfortable for you on test day. Also, wear a watch and monitor your time, making sure not to spend so much time on any given problem.</p>
<p>On the reading, read EVERYTHING quickly and then go to the questions. I have seen advice on here saying you should pretend that what you are reading is the most interesting thing in the world, and for the most part, this suggestion really helps- you’ll be more focused, and you’ll read with comprehension, reducing the number of times you have to go back to look up an answer (inevitably saving you time). You should either remember/be able to infer the answers based on what you read, or you should be able to recognize where in the passage you need to look for the answer.</p>
<p>On the science, do not read the introductory material. You only have 35 minutes (an average of 5 minutes per section), so this does not give you any time to waste. First, quickly look at whatever graphs or charts they provided for you and try to discern how the variables interact (oh, as x increases, y decreases, or something to this effect). Then just go to the questions, identify which graph or chart or data table they want you to use, and answer the question accordingly. </p>
<p>Practicing these sections under normal (or even harsher) testing conditions will really help you to improve your score.</p>
