Your raw score is out of 190 points, even though you answer 200 questions. This is because ten questions are experimental and count for no points.jumpingjack wrote:Can someone explain this to me like I'm 8 years old?Tanicius wrote:
70% is taking into account the 5+% bump you get from the 10-15 added points from scaling the score.
To account for those experimental questions, your raw score will automatically receive a 10-point boost on the real test. Note, however, that any questions you got correct on the experimental questions will also be subtracted from your overall score.
The NCBE will also award extra points for any questions they knock out of contention after scrutinizing statistical difficulty. What they're looking for are mistaken/inaccurate/unfair wording they failed to catch in their questions. The amount of knocked-out questions will typically be between 0 and 5.
Add the knocked-out points to your score, plus the 10 experimental question points, and you're realistically looking at boost of between 10-15 for your final score, depending on the test. That is called your "scaled" score.
