In computer science and formal methods, a SAT solver is a computer program which aims to solve the Boolean satisfiability problem.On input a formula over Boolean variables, such as "(x or y) and (x or not y)", a SAT solver outputs whether the formula is satisfiable, meaning that there are possible values of x and y which make the formula true, or unsatisfiable, meaning that there are no such ...
In the U.S., the SAT Subject Test in Mathematics Level 2 (formerly known as Math II or Math IIC, the "C" representing the sanctioned use of a calculator), was a one-hour multiple choice test. The questions covered a broad range of topics.
The test is intended to assess students' readiness for college. Historically, starting around 1937, the tests offered under the SAT banner also included optional subject-specific SAT Subject Tests, which were called SAT Achievement Tests until 1993 and then were called SAT II: Subject Tests until 2005; these were discontinued after June 2021.
Examples of these tests include entrance examinations used for admissions to institutions of higher education, such as college (e.g. the SAT and ACT), business school (the GMAT), law school (the LSAT or LNAT), medical school (the MCAT), BMAT, UKCAT and GAMSAT and graduate school (the GRE) and qualifying examinations for admission to gifted ...
The Stanford Achievement Test Series, the most recent version of which is usually referred to simply as the "Stanford 10" or SAT-10, is a set of standardized achievement tests used by school districts in the United States and in American schools abroad for assessing children from kindergarten through high school. [1]
However, tests may also award partial credit for unanswered questions or penalize students for incorrect answers, to discourage guessing. For example, the SAT Subject tests remove a quarter point from the test taker's score for an incorrect answer. For advanced items, such as an applied knowledge item, the stem can consist of multiple parts.
A variant of the 3-satisfiability problem is the one-in-three 3-SAT (also known variously as 1-in-3-SAT and exactly-1 3-SAT). Given a conjunctive normal form with three literals per clause, the problem is to determine whether there exists a truth assignment to the variables so that each clause has exactly one TRUE literal (and thus exactly two ...
[35] [36] In 1993, the College Board changed the name of the test to SAT I: Reasoning Test and changed the name of the Achievement Tests to SAT II: Subject Tests. [37] Together, all of these tests were to be collectively known as the Scholastic Assessment Tests. The president of the College Board at the time said that the name change was meant ...
