" Hey, what do you think she meant by that?" Mo Qiang asked as she looked at Mo Xifeng, her pupils shaking with fear as she clenched her fists angrily. " Does she mean to say that Yin Fu performed so badly that he got a score so low that the Headmistress did not even imagine?" 

When she thought of all the millions of gold coins that she dumped in the academy to get Yin Fu a shot at the exams, Mo Qiang felt like she was going to get a heart attack. 

Mo Xifeng was not aware of Yin Fu's standards either. She only knew that when their family was exiled Yin Fu was studying in the cheapest college of the Imperial Star, though that college had its own prestige compared to the Imperial Law and Order it was way behind. 

She pursed her lips and then patted Mo Qiang on the back before saying, " Don't worry, I bet that brother-in-law wouldn't have let you down…maybe?" 

What was that questionable maybe added in the last?
