These are online or printed collections of solutions for standard algebra assessment books used in grades 7 through 11. Teachers use these books to give "control works"—formal tests that typically happen at the end of a chapter or semester to grade a student's progress. Common Sources

: Usually 2 or 4 identical-difficulty versions (Variant 1, Variant 2, etc.) to prevent copying in class.

(Макарычев): Often includes both textbook exercises and separate assessment manuals.
