I did orals for all of my licenses . It's not a perfect system but a lot better than multi guess . It also allows examiners to gauge the personal qualities of the applicant ( the old application form used to have a section where a LAE had to sign that the applicant was " of a suitable character " or words to that effect ) .
These days you just have to pass the modules .
Too many LAE's are prepared to sign anything , just because the shift manager says so .........
