Ya i received one letter that stated that, have to go to 'ns.sg'
to do some document, select the uniform, boots etc... they asked to
book a appointment date for check up too, but i book the day is on
friday, but i'm still studying how?
Medical checkup is always on a weekday. Try to book appointment
at a time during your holidays or if u must skip classes, find a
time where you have less or not important classes since the entire
medical checkup process can take 3-4 hrs.
