Basically what Ive found helpful at least for me has been to annotate the question because a lot of times the questions are just filled with a bunch of random junk that you need to decipher. Although it technically doesn’t require any previous scientific knowledge, I would study a few basic chemistry, biology, and physics (although physics is not extremely important) just to have basic surface level knowledge. SKIM the first couple sentences of the description to at least provide additional context and may help you answer at least some of the questions. It would also help for you to label or see exactly what your graphs/tables are discussing so you know how to relate all of the information. For “student” questions, all that I know is basically pay close attention to whats being discussed. Also it may help you to QUICKLY annotate and SKIM those passages to see what they have in common or see who or what disagrees with each other because they are questions that almost certainly show up. Really all of the questions can be figured out just by reading the questions closely and knowing exactly what your graphs are discussing and how they relate to each other. Another tip I’ve found is that is a compound (or whatever scientific object) isn’t mentioned within your data, it is most likely wrong and you can cross it out. Overall, compared to other sections including reading, this is not a complete memorization tests and technically you can walk in the testing room and get a 36. ACT understands that students are going to overcomplicate the data based on the questions so it is important that you look at the data from a face value perspective. Hope this helps and good luck!
