Inconsistency in GMAT scores
Hey I scored 715
Getting q-8,18 wrong in quants scoring 87
Getting q-4,7,23 wrong in va scoring 85
Getting q-13,16,19,20 wrong in di scoring 84
Now this was my second GMAT attempt and I've given 16 tests including official attempts and official mocks across which this was the most obscure result.
I know the test is adaptive and hence some variation is possible but this was kinda extreme
I've previously scored 87-87-86 in va with 4-4-5 mistakes and here I got 85 iwth just 3
In di I've scored 84-86 with 6 mistakes 84 with 6 in last attempt and here I got stuck at 84 with just 4 mistakes
In quants as well in all 4 mocks where I made 2 mistakes I got 88
Now before you hastily pass judgement there's a reason I mentioned the ques no. Which I got wrong as question's position give some information about the adaptive trajectory account for it
And I ran models on google collab which came in support of my intutive observation I also used leave-one-out/cross-validation so the historical fit wasn’t just each observation helping predict itself
Once again I know data of just 16 tests is far from enough to reverse engineer a scoring algo but strong enough to produce an informative out-of-sample prediction and flag this attempt as a clear outlier relative to my historical pattern.
Has anyone in recent attempts seen a similarly large mismatch between their error pattern and sectional score?
