Army BMT enhanced intake for JC students are usually on Jan and
April. These people only need to serve 1 year 10months. So lets
just look at april batch, April batch enlistees will ORD in Feb.
Minus away their annual leaves and off, they can start schooling in
January. Anyway, its not compulsory to attend university's lessons.
Some modules may require you to attend or else you may lose up to
10% of assessment grades but the university cant expel you.
Generally in University like NUS/NTU/SMU, most students will
start their courses in July/August. However, nowadays more and more
students are taking the january intake cos there is no disadvantage
at all. All ESSENTIAL modules are offered in every semesters. You
will graduate in december, a period of time where there are much
less fresh grads than June.
