Instructions. Questions are arranged from easiest to hardest and are intentionally interleaved across all five sections so that concepts reinforce one another as you progress. Select your answer for each question; a short explanation appears immediately below your choice. Use the Hint link only if you are stuck — try the concept check first. This booklet may be completed on screen or printed; an answer key is included on the final page of the printed version only.
