Every vector space is a free module, [1] but, if the ring of the coefficients is not a division ring (not a field in the commutative case), then there exist non-free modules. Given any set S and ring R, there is a free R-module with basis S, which is called the free module on S or module of formal R-linear combinations of the elements of S.
This is a list of primary and secondary school tests. Tests available at the end of secondary school, like Regents Examinations in New York, California High School Exit Exam, GED across North America, GCE A-Level in the UK, might lead to a school-leaving certificate. However, other tests like SAT and ACT do not play such roles.

Kaplan Publishing focuses on print and digital test preparation and reference resources.
Hence when n = 1, R is an R-module, where the scalar multiplication is just ring multiplication. The case n = 0 yields the trivial R-module {0} consisting only of its identity element. Modules of this type are called free and if R has invariant basis number (e.g. any commutative ring or field) the number n is then the rank of the free module.
A group of students preparing for a test. Test preparation (abbreviated test prep) or exam preparation is an educational course, tutoring service, educational material, or a learning tool designed to increase students' performance on standardized tests.
