What about SIT or SUTD? They offer degrees too.
I'm taking UoL economics.
The approach is very different from what you learnt in A levels. It is highly mathematical and uses more of abstract models than case studies. I know of many students who got an initial shock that their favorite subject in JC suddenly become like an alien language. However I only speak for UoL.
There are also other universities in SIM and their style of teaching and assessment varies. Economics can be studied in RMIT, University of Buffalo.
Truth to be told,
career prospects are really dependent on how you prepare yourself from the moment your JC ends: it is a combination of personal responsibility, finances, CCA, grades, external accomplishments, networks and luck.
For example, if you are graduating in June 2016 but you only start sending resumes in May 2016, it is your fault that you remain unemployed till August 2016.
SIM does provide career help through
Enrichment Courses: writing resumes, interview, etc.
Coordinating Internships
Networks
They also post job openings on student portals.
