No, it has nothing to do with the selection process. Actually, some candidates approached Federal Ombudsman(Mohtasib) that they were not issued Roll nos. even though they were shortlisted for the test and NTS has admitted that 122 candidates were missed due their mistake. Now, either NTS will conduct the test again or there are more chances that only those 122 candidates will be called for test by NTS and then their results will be sent to CAA.
Secondly, their was one mistake in the Pink Book but I think one mark will not affect the overall result or merit. May be, candidates having Pink book will be given one grace mark.
