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.).
When break times are included, the ACT Plus Writing takes a total of 3 hours and 50 minutes. With breaks but without Writing, the ACT is only 3 hours and 5 minutes (or 3 hours and 25 minutes if you have to take the fifth experimental section). Some students dislike the breaks in between sections.
