GED® Algebra: Skills Hardening & Challenge Practice

A high-difficulty challenge course that hardens your algebra. It assumes you already know how to solve equations, inequalities, functions, and systems, and trains you to handle them under test-day pressure: long multi-step chains, mixed topics in one problem, sign and distribution traps, no-solution and infinitely-many cases, and word problems that hide the equation. Every practice answer is worked step by step and names the trap most students fall into.
