Consider these:
Course
A
1) Are you in a hurry to complete the degree? How much can you save
for the difference of 1.5 yrs?
2) Which organisation are you intending to apply for jobs... If you
are looking for Government sectors then better choose Course
B
Course B
1) How recognised can it be than local university... unless you are
talking about top overseas university e.g. Cambridge etc...
2) Longer duration normally equal to more effort, money and time
being involved... can you afford it?
Apart from the above, the are many factors that you need to
consider like what are the modules in each of these courses... and
are they what you want to learn or interested to learn... How much
help are they of help to you in your future careers...
Most importantly is that you much spend more time looking into the
two courses and also into more other courses offered by other
universities... and don't jump into it... coz the degree is going
to stay with you for the rest of your life...
Good Luck...
