Is there a way to tell which Module 2 you got?
Short answer: no. Bluebook doesn't flag it anywhere. No banner, no label, nothing in the interface that says "easier" or "harder." The app just hands you the next module and moves on like nothing happened.
The score report afterward doesn't help either. You get a scaled score between 200 and 800 per section and 400 to 1600 total. That's it. There's no line that says which version of Module 2 you sat for, and no way to back it out from the number alone. If someone online tells you otherwise, they're guessing too.
Solve x^2 - 9 = 0.
Why it feels like you can tell
Plenty of students walk out convinced they know. Module 2 felt brutal, so it must've been the hard version. Or the opposite: breezed through it, so it had to be the easy one. The feeling is real. The conclusion drawn from it usually isn't.
Difficulty is a moving target, not a fixed one. You're more tired in Module 2 than you were in Module 1, every single time, because you've already been testing for a while. Nerves spike or settle depending on how the first module went. And Module 1 itself mixes easy, medium and hard questions, so your sense of "how hard this test is" was never a clean baseline to compare against in the first place.
Two students can sit the exact same hard Module 2 and walk out with opposite impressions. One finds it energizing. The other finds it exhausting. Neither impression tells you anything official.
What actually decides which module you get
Routing runs on your Module 1 performance, and only that. Reading and Writing routes on its own Module 1. Math routes on its own, completely separately. Doing well on one has zero effect on the other, so don't read anything into a strong Reading and Writing section when you're trying to guess what happened in Math.
What matters inside that module is accuracy, not speed and not strategy. Racing through Module 1 to "save time" for later doesn't earn you a harder Module 2. Answering carefully and correctly does. College Board hasn't published the exact threshold, and nobody outside the company actually knows it, so treat any specific cutoff number you see quoted online as made up.
Why guessing mid-test is a bad idea
Here's the problem with spending Module 2 trying to diagnose which version you're in: it changes nothing. By the time you're in it, routing already happened. You can't un-finish Module 1. All that mental energy spent comparing this module to the last one is energy not spent on the question in front of you.
Treat whichever Module 2 shows up the same way: read the question, work it, move on. If it's genuinely rough, that's not a signal to panic, it's just what a harder module feels like. Everyone taking the harder version is in the same boat, and the scoring already accounts for that difficulty. Since there's no penalty for a wrong answer, never leave one blank. A guess beats an empty box every time.
What you can actually control
Since Module 1 sets the ceiling for the whole section, give it full effort from question one. Don't hold back, don't rush to finish early, don't treat it like a warmup for the "real" test. It is the real test, maybe more than Module 2 is.
Practicing under the real adaptive structure matters more than most students give it credit for. A test that doesn't actually route between modules gives a softer, less honest picture of where the score stands. StudyPebble's free full-length adaptive practice test at /sat/practice-test runs the same module-to-module routing, with no account needed, so the practice feels closer to test day than a flat, non-adaptive set would.
