To understand the possibility for *your* specific situation, you should:
* Check the PTU's official examination rules and regulations: This is the best place to find any formally stated policies regarding borderline cases.
* Contact the PTU examination department directly: They can provide the most accurate and up-to-date information.
* Consult your department or program coordinator: They will be aware of any past practices regarding close-to-passing grades.
Don't rely on the hope of grace marks; aim for passing grades through diligent study.
