DD10 was supposed to take the MAP math yesterday and could not due to technical difficulties. This has happened to my DD16 with a different computerized test - fortunately it was a "practice", but twice the test kicked her out and she had to start all over again.
The test would need to save after each question, and I don't know if it does that, or if the school can set things so that it saves after each question.
Oh well, not as bad as the guy I knew who took his PE (that's professional engineer, not physical education) exam. Thought he did really well then was notified that the tests were being stored in a building prior to grading, and the building burned down. That's an eight hour test, and he had to study again and take it six months later.
