Use questions before passive review

Start with a short set, mark the misses, then review the exact topic that caused the miss. This keeps study time tied to evidence from your own answers instead of a vague topic list.

Sample 1

What is a bid bond mainly used to support?

  1. The owner's obligation to accept the lowest submitted price
  2. The contractor's obligation to pay every subcontractor after award
  3. The surety's guarantee that all project work is defect-free
