Both tests assess similar skills, but the ACT tends to emphasize reasoning and science more than the SAT. Choose the test that feels more comfortable for you. SAT is now offered only digitally, and its two math sections compose 50% of your score. If you're a walking calculator, SAT might be better for you (and we are ready and able to help!). If not, some students prefer the ACT, where math is only 25% of the score.
