why don't you apply for higher nitec..
get a better higher gpa then apply for poly..
getting a diploma from local polytechnic is impossible with a gpa of 2.0 and dont expect to be accepted into higher nitec course.
the only way to get a diploma for your case in the event that you fail to enter a higher nitec is to sit for private 'o' level.
get a private degree from MDIS better
u need higher nitec...nitec gpa 2 cant get u anywhere...
