Hi Charlotte825,
You're definitely not alone in experiencing this—test anxiety and difficulty staying focused under pressure are incredibly common among GMAT test-takers, even those who've prepared diligently.
It's fantastic that you've started meditating and working on stress management; these habits do make a difference over time. However, translating calm practice into actual test-day clarity is often the hardest part.
One helpful technique is practicing specific mindfulness or grounding exercises during the test itself: when anxiety spikes, pause for a moment, take a few intentional deep breaths, and consciously reset your attention to the immediate task rather than the timer or your overall performance.
Additionally, adjusting your mindset to accept some degree of discomfort can relieve pressure—it's normal to miss questions or feel uncertain during the test, so reminding yourself that perfection isn't required can alleviate stress. Lastly, many have found success by visualizing the test experience positively beforehand, reinforcing a sense of control rather than being overwhelmed. Keep reminding yourself of your progress, trust your preparation, and know that incremental improvements in managing anxiety will reflect positively on your scores.
