The SAT and ACT have different ways of scoring. Points are deducted for wrong answers on the SAT; they are not deducted for wrong answers on the ACT.
There are strategies for whether or not you should guess on the SAT if you can narrow down your choices to fewer than four answers. On the ACT, you are not penalized for guessing, even if you guess wrong!
The next ACT test is June 9th – for registration info, click here.
