Lets take 2 merit seats of DDs. 20 candidates were called for psychological test. Out of these 20 if 5 passed the test then out of these 2 with top written marks may be called for interview against merit quota and the rest 3 may find adjustment against their provincial quota. Naturally those called for psychological test against merit quota must have higher written marks than those called against provincial quota. And if those called against merit seats could not secure merit seat then they will displace provincial quota candidate of his place.

And if all 20 failed then candidates with highest marks though called for psychological test on provincial quota will be called for those merit seats. Leaving place for candidates with low marks to fill the provincial quota.
