The mental state and actions during the exam are described as follows: He was so nervous that his palms were covered in sweat. He kept taking deep breaths to try to relieve his stress. His eyes were fixed on the test paper, and from time to time, he scanned each question in an attempt to quickly understand and answer. His lips were tightly pursed and his fingers were trembling as if he was trying to hide his uneasiness and anxiety. After answering one question, he nervously looked forward to the next question's answer. He kept repeating the answer in his heart, trying to make his answer more accurate. After he answered the question, he became even more nervous and his breathing became even more rapid. His body trembled slightly as if he was afraid that his mistake would be discovered. When he finished all the papers, his mood finally calmed down, but his heart still felt extremely anxious and uneasy. He took a deep breath and tried to relax himself. Then he handed in his paper and left the examination room.
