Beyond technical knowledge, mental preparedness plays a vital role in exam success. Candidates should develop strategies for managing time, handling difficult questions, and maintaining focus throughout the 105-minute duration.

Practicing under timed conditions with mock exams helps build endurance and confidence. Additionally, developing a systematic approach to questions—reading carefully, eliminating incorrect options, and pacing responses—enhances efficiency and accuracy. Visualization techniques and mindfulness exercises can further reduce anxiety and improve concentration.
