Anybody has any idea what are the career prospects if I completed my OBU ( without P levels ), I'm planning to pursue P levels on part time while working.

AFAIK all papers with 40-49 will go through a second round marking to try to push up the marks, if you get between 40-49, usually your first round marking is lower.

Anybody knows where to take tuition if I were to work in PJ?
work fulltime study part time.

I know sunway and kasturi is near PJ at Subang but are there other options other than these 2? preferably in PJ.
