Cover the whole term, not just one chapter
The mistake that sinks a generated exam is feeding it a single chapter and calling it a final. A cumulative exam has to sample the entire term, so upload the material for every unit you want on the test, not just the last one. When you combine several readings, the generator can write questions across all of them, and you can then check that each unit shows up in the finished paper.
Weighting matters as much as coverage. If you spent three weeks on one unit and one week on another, the points should reflect that. Build the blueprint first, decide how many points each topic earns, then pull questions to fit. This is the same discipline a good test bank enforces, which is why many instructors keep a running pool and assemble each exam from it. You can turn a semester of notes into that pool with the notes to quiz converter and add the questions as you go.
For a high stakes exam, make two forms. Generate more questions than one test needs, then split them into two versions that cover the same objectives at the same difficulty, and shuffle the option order. Two forms that read differently but measure the same thing make copying from a neighbor pointless, and neither student gets an easier paper. When you want students to practice before the real thing, hand them a separate set from the same material as a practice test.
