Looks like there's quite a few ntu fellows here.
faizal..keep trying...do make a call to the schools to check it out..there are times when they have one or 2 extra vacancies because some opt to drop the course.
the entry prerequisite for the business faculties are generally more stringent particularly for poly graduates. it used to be average As (like the COM holders) poly grads who were granted the vacancies. However, they are opening up more slots now to cater to the average students too.
Entry to the engineering faculties are slightly easier for poly grads as the universites tend to favour the prior hands-on skills that poly grads with engineering diplomas have. it's possible to secure vacancies with average Bs. The intake is definitely larger for engineering faculties. As for business faculties, it used to be quite miserable, 10-15 for all then-4 polys out of 600+ intake. That was during my batch back in 2002/3. Hope it helps. Thanks.
