My screening marks were good enough to qualify for descriptive stage and in my opinion, I also did well in descriptive exam. And I failed in descriptive test. I do not have any reason to suspect the NTS intentions let alone any solid proof. There are many on this forum who succeeded to qualify for next stage which in itself negate the idea of any systematic deception on part of NTS. Therefore, I strongly urge to failures like me to stop whining and try harder next time.
Remember, It was the same assessment team (NTS) who passed all descriptive test qualifiers. If someone insist that the NTS was unfair to him/her in descriptive then by the same logic NTS was also unfair to let him/her pass in screening test.
