Like Reasoning Through Language Arts, Science places a lot of emphasis on comprehension of reading passages. In general terms, the passages delve into biology, chemistry, physics, earth, and space. Your ability to understand what you have been given to read is more important for answering questions than tapping into an encyclopedic memory.
The TI-30XS MultiView Scientific Calculator, the official calculator of the GED, will be needed for some questions in the Science test.
