failed 640-822 today. Score 792, passing score 804. The problem was that i was not able to answer so many question for that amount of time. I think it is related that English is not my native language or i think too slow

.I had left approximately 4-5 questions without answer, including simulator.
Is there any additional time:) for exam or any suggestion what can i do to answer faster? I just feel like it is not possible for me to process that amount of question for that time.
