For the past decade or so, the SAT has come under increasing scrutiny for its confusing structure, trick questions, and obscure vocabulary. Meanwhile, the ACT is often seen as the fairer test, more closely based in what students learn in school.
As you might have heard, the College Board undertook a radical overhaul of the SAT that went into effect in March 2016 and, in many ways, made it much more similar to the ACT. Adding to the confusion is the fact that ACT, Inc., also made some minor changes to the ACT.
What are the main differences between the current versions of the two tests? The short answer is that the SAT and ACT are now quite similar. The changes have eliminated many of the two tests' major differences in both style and content. Nonetheless, there remain important variations—some long-standing and some newly introduced.
