Agree with @byoung2 about getting a good night's sleep. Try to keep yourself calm and focused for the exam. Give it your best shot, and don't feel afraid to complete the test even if you feel you haven't done well. IMO, that's a temptation that's hard to overcome no matter how well you're prepared. FYI: I took the test a few years ago (when the scoring system was based on 2400 points. Took the exam thrice & scored 1640, 1960, and 2340)
Agree. Pick a name that best reflects what you'd like your customers to perceive your brand as, and not based on SEO considerations. If you make it work for humans, the machines will follow ;)
