There should not be a difference in the impact of making changes to the answers on the test.

The test simply recalculates the score based on the three parameters of every question and likely the penalty you observed was either due to question being on the easier side or question having a higher certainty parameter or discrimination and thus having a higher weight among other questions.

Without confusing everyone and getting very technical, the answer change should have equal impact... logically. But honestly I feel like it would be nice to experiment with it though I don’t see a reason why it would not be...
My logic is based on the idea that if you originally answer a hard question correctly and then change it to an incorrect answer during review, the penalty could be greater than the benefit gained from changing a medium-difficulty question from incorrect to correct.

Since each response influences both my score and the difficulty of subsequent questions in an adaptive exam, this seems like an important aspect to consider. If that is how the algorithm works, it would imply that test-takers should only change an answer when they are highly confident that their revised answer is correct; otherwise, the risk of hurting their score could outweigh the potential benefit.

Unfortunately it’s really hard to tell and predict things because there are hidden question parameters that we don’t know.

However, a medium or easy question has a bigger impact on reducing your score than getting a hard question incorrect though if there is a very small number of hard question so like if they’re only four questions in the entire test and you got one of them wrong then it would be a bigger impact... but usually harder questions the system expects you to get them wrong and doesn’t penalize you as much as with easy or medium

Thank you so much for insightful discussion this also looks correct

This much unpredictability 😅 we don't how many hard level questions will come and that may also change algo and score 😅😂
We should just forgot about the algo i feel so 😅

Will keep that in mind, but suggest me this would it be a wise idea to change the answer in review for the question i don’t know how to solve or have met with a road block?
