Env. Science — Exam-Skill Drills
10 items across 4 skills · answer, then read why the other options fail
Roughly half of an AP STEM exam is not asking what you remember. It is asking whether you can pull a claim out of a data table, spot the missing control in someone else’s procedure, carry units through a calculation, or read a slope off a graph. These drills isolate those four skills so you can find the weak one.
Skills covered: Units & sig figs · Data analysis · Graph reading · Experimental design.
