I actually made a loss the day I attended the course as they
still made us pay the full rental for the day.
30 persons attended this optional/compulsory course which means
$11400 per course conducted by 1 instructor (from Kaplan) for max
of 8 hours only which means $1425 per hour.
Compare this with the essential taxi course by Singapore Taxi
Academy which only cost $350 for 10 days which includes course
materials, lots of maps and examination fees which leads to a taxi
license (which means full pay) for taxi drivers (average of only
$25-$28 per day after factoring in course materials and examination
fees).
