In reply to your questions:
1) Does taking psychology in uni (local and overseas) require me
to be in arts or science?
It doesn't matter. Psychology is under the Faculty of Arts and
Social Science.
2) is geog like econs?
No. Not at all.
3) How long do i have to study for psychology?
It depends on which university. In Singapore, it's 3 years for
Bachelor without honours, 4 for honours.
4) For arts, is it still possible to do clinical psychology
Can't answer that, sorry. But you might want to be aware that
psychology is merely a "social science" major. You are not allowed
to practice "medicine" through this major and you are not allowed
to give patients prescription unless you go on to a phd level
(doctorate). Basically, many students who took psychology as a
major and didn't further their studies after 3 or 4 years, don't
find much opportunities to make use of their degree later unless
they take on jobs related to social work.
Further comments:
poly also can go uni. But at the end of the day, some degree
holders can mug but cannot work, what's the point.
Although it's true that not all graduates is as capable at her
job as he/she was in school, I still feel that it isn't easy
getting good grades in a country like Singapore. If he/she was able
to do really well in school, it does show her ability and potential
to some extent.
And believe it or not, academical theories are underrated. It is
more useful in life than just helping you to achieve good grades in
school.
On another hand, I also dislike it when underachievers in school
make comments like work experience is a lot more important than
having a good degree. Personally, I used to be below average when I
was in school but I do appreciate other people's intelligence,
determination and hard work. And many top scorers are not just
"muggers", they actually do have the intelligence to help them
achieve further in life when they come out to work.
