Hi karthikdetermined,
The scoring algorithm on the Official GMAT is far more complicated than most people realize. Since that algorithm is proprietary, no GMAT company has an exact match for it, thus CAT scores can vary a bit based on the 'biases' involved in their respective designs. While the most realistic CATs available are the 6 from GMAC, the 'blocks' of CATs available from Kaplan,
MGMAT and Veritas are all 'close enough' to the real thing that they'll give you a reasonably accurate score assessment (assuming that you correctly use the CAT).
GMAC has publicly stated that the Official Score that you earn on Test Day is within +/- 30 points of actual ability. Assuming a similar 'swing' in how your CATs function, your 3 CAT score results show that you essentially performed the same each time - and these scores are similar to your prior Official GMAT Score (from 4 years ago, which you descried here:
https://gmatclub.com/forum/my-debrief-6 ... l#p1323297). Thus, it stands to reason that you're still scoring at the same high overall level as before.
GMAT assassins aren't born, they're made,
