After you remove or transfer your SIM card, insert the tray completely and in the same orientation that you removed it (it will fit only one way). Use only the SIM tray that came with your device. For example, a SIM tray from an iPhone 6s will not fit in an iPhone 7.
Total test time is 205 minutes if taking the Writing/essay. Without the essay, the ACT is 155 minutes actual test time. Individual sections are always in the order of: English (45 mins.); Math (60 mins.); Reading (35 mins.); Science (35 mins.); and, optional Essay (30 mins.).
The ACT English Test assesses your knowledge of English grammar and writing. On the test, you will have 45 minutes to answer 75 questions. That may seem like a large number of questions and relatively little time, but the English Test, more than any other ACT Subject Test, assesses what you already know, rather than what you can figure out if you are given certain information.
