4. Use shortcuts and techniques: Learn and practice shortcuts, formulas, and problem-solving techniques specific to the Commerce exam. These will help you solve questions quickly and accurately.

5. Practice time-bound mock tests: Regularly attempt mock tests under timed conditions to improve your speed and accuracy. This will also help you identify areas where you need to improve.

6. Review and double-check: Once you complete the exam, go back and review your answers. Double-check for any errors or mistakes you might have made in the rush. Correct them if possible.

7. Stay focused and avoid distractions: During the exam, stay focused and avoid any distractions that may hamper your speed or accuracy. Concentrate solely on the task at hand.
