It's still equivalent to "normal" tests, because the cost of skipping and the cost of answering incorrectly are the same. A test in that format with N questions and a test in the normal "1 point for a correct answer, 0 for anything else" with N questions are related as follows, assuming C correct answers:
Score in the +5/-4 system: 5 C - 4 (N-C) = 9 C - 4 N
Score in the +1/0 system: 1 C + 0
It's basically a "9 points for a correct answer, 0 for anything else" test that simply starts with a score of -4 N.
It's very similar to the difference between Celsius and Fahrenheit.
- dylan604 3y agohow many normal tests would ever result in a negative score? it's quite devastating to any shred of morale one might have. test had 80 questions so a max score of 400. i personally never witnessed someone receiving anything over 300. you're really trying to make something into something it is not. for the curious, here's an example test: https://bryantheath.com/files/2021/02/Q104.pdf https://bryantheath.com/files/2021/02/Q104.pdf edit: you only get 10 minutes to take the test
- Dylan16807 3y ago> It's basically a "9 points for a correct answer, 0 for anything else" test that simply starts with a score of -4 N. But it's not. Skipped questions before your final answer get a bad score, while skipped questions after your final answer get a medium score. If you take a blank test and answer the last question only, your score drops by hundreds of points. No normal test does that. That's how it penalizes skipping around.
