Can I ask for bonus marks?
Why do you feel like you deserve bonus marks?
Because I've worked hard for this matriculation exam
It's understandable to want recognition for putting in hard work. If the situation calls for it, feel free to ask. If not, don't expect to get any in return just for asking.
I want gratitude. I deserve respect for my hard work. Matric was my first degree.
I think it is most important to know you are proud of yourself. The level at which others express congratulations is up to them.
