3. Strategy for Hard Items
GED® Mathematical Reasoning: Full-Length Practice Exam (Level 2 - Advanced) · preview lesson
Hard GED® questions reward a calm, written process more than speed.
- Show each step. Multi-step items (percent-then-percent, ratio-then-total) are where careless mistakes live. One line per step.
- Backsolve when you can. If the choices are numbers, plug them into the original problem -- often faster than solving a quadratic or rational equation.
- Estimate to catch calculator slips. A quick estimate flags a decimal in the wrong place.
- Watch the sign flip. Multiplying or dividing an inequality by a negative reverses the direction.
- Re-read the last line. Hard problems often ask for the original price, the largest angle, or the other leg -- not the value you just computed.
- Flag and move on. Don't let one brutal question eat five minutes; guess, flag it, return later. No penalty for a wrong guess.
Quick Check
When you divide both sides of an inequality by a negative number, what must you do to the inequality sign?
Dividing by a negative reverses the direction of the inequality.
