Nope, no writing. Just four sections IIRC, Reading, English, Math, and Science. You get a score out of 36 for each section, and these are composited together. To give you some idea, a 1310 SAT is about a 30 ACT.
ACT is easier than the SAT imo, not by a whole lot, but the additional english sections and stuff help balance out my math scores. I took the SAT but didnt send it to schools
