Arabic to English Tech/Engineering Education / Pedagogy Syrian University certificate

I am translating a degree certificate for an engineering student (Syrian) and it lists all the subjects and gives the marks. On the subjects where the student got less than 50 marks it says:

(٤٨ + ٢ / ١٠٠ فقط خمسون ولا غير (م

With the marks where the student got over 50% there is no (m). It just says e.g. 55/100 fifty five only. But on all the ones where he got under 50 and they have added 1 or 2 points to make the score up to 50, it has (m) after it.

Does anyone have any idea what this could stand for?

Many thanks!
