As we know in Australia a student can choose a variety of subjects from different departments.
For example a student can do extension two Mathematics and extension two English.
These are two subjects at the two ends of the spectrum, one preparing you for science,
engineering and other courses based on mathematics but the other preparing you for tertiary
courses in the field of humanities.
Is not this a waste of time and energy for a student who will eventually
choose one direction for their university study and career?
Is not it more efficient if high school subjects were divided into certain groups with
each group containing similar subjects and each student were allowed to choose the subjects
from the same group?
This has been the practice for many years in many different countries.
