RE: StudySmart Percentile Rank Issue

Andrea Tinnen reported a day ago (Mon, 5 Jun at 12:52 PM) via EmailTo: operations@barbri.com, barbriswat@barbri.comHello, So this student completed the Torts Set 1 question set 6 times (in the space of 2 hours) on 5/28/17.  The last time that she completed the question set, she got 50%, hence the 50% shown for her score.  The score column shows results based on the latest question answer (i.e., if a question is answered multiple times, the result is shown for the most recent time that they answered it).  The percentile rank however, is calculated a little differently.  It is calculated based on correctly-answered questions.  So if you take a question 5 times and answer it correctly the third time, but incorrectly the other four times, the correct answer is counted (regardless of the incorrect answer(s) in later tests) in the percentile rank calculation.  You can see that the second time the student answered the question set, she got everything correct.  So that is what is being counted in the percentile rank calculation (to make it 99.9%).  This difference in calculation has existed for years.  I would venture to say that we haven’t seen this particular issue before because students aren’t doing question sets multiple times in such a short time period, with sure a difference in scores.  I’m still not sure what the student was doing here…Regardless, I hope this explanation makes some sense.  We can discuss updating these calculations after the course is over; they are complicated and will require development work and testing time.  I’ll have Zhivko assign the ticket back you and then you can close it.

OTRS Ticket#2017060250000011 — StudySmart Percentile Rank Update Issue

 Hi Dev,

#1399182 Gina Leahy contacted CST regarding her percentile rank for Torts Set 1 in Studysmart.  She scored 50% correct on the assignment, but her percentile ranking against 6373 students shows her at 99.9%.  I believe her actual percentile rank should be in the 40-50% range.  I checked some other students (ex. 1076069 Leslee Byron) that completed Torts Set 1 and they scored 61.1% correct and they are in the 55.5% percentile ranking.

Will you please take a look at Gina's account and determine why her percentile ranking is not being updated?  Screenshots are attached to the OTRS ticket.

Thank you,

Brian Haskew
