What happened to the 98 applicants between episode 5 and 6?
The wording of the examiner of the first phase is odd, but he was saying he thought 50 would pass and then corrected his statement to only 10 would pass.
There were still 148 applicants but he was stating 2 numbers of how many he thought would pass.
(also in ep5 the narrator stated 220, but I figured that was a typo)
