Science primarily allows you to hack terminals using a mini-game. Certain terminals have different difficulty levels, and different Science skill levels are required to hack them. The difficulty ratings and skill levels are: very easy (0), easy (25), average (50), hard (75), and very hard (100). Your Science skill relative to the difficulty rating affects how hard the minigame is (at Science 100, average terminals are a breeze, presenting only about 5 possible passwords). Harder terminals have more words, longer words, and fewer brackets.
