Everyone else in the classroom started to do the questions.
The surrounding area was so quiet that Ye Ci could even hear the sound of her heart beating nervously.
Her palms were also sweaty.
For a moment, she took a deep breath and tried to calm her mind.
This exam could not be avoided, so she could only try her best.
She then picked up her pen and looked at the first question.
It was a question on thermal energy conversion.
Ye Ci stared at the question for a while and worked it out on her draft paper.
Zhou Fei had taught this type of problem in class before, but it was tough because the values in this problem were very tricky and required a lot of calculation.
After a while, Ye Ci's answer was a negative number.
This was obviously incorrect.
She frowned and went back to check the steps, not knowing where the problem was.
