hey, if you read my debrief you'll see i felt exactly the same way. i think it's perfectly normal to feel stressed out the night before... even the day of your test. however, you need to channel your inner strengths by the time you get to the test center. do whatever it takes (meditate, work out, go running, read, listen to music) to get you in the 'zone' (in the test taking mentality). if you let your emotions get the best of you, then your score will definitely be affected.
you know whats funny.. i barely told anyone i was going to take the test also. only my girlfriend knew.. i didnt even tell my best friends or my parents. i did this because i didnt want any extra pressure... so if you think of it that way, then that should take off a lot of the extra pressure on test day as well.
you know whats a good mental image/ thought to have when you walk into the test? i dont know if you've ever watched wrestling or boxing, but think about the fighters when they walk into the ring. they have thousands of people watching in the stadium, millions watching at home, and they walk triumphantly into the ring to begin their championship bout. their intro music is playing, lights are flashing, and thunderous applause fills the arena. just picture yourself as the boxer/wrestler and the arena is the GMAT test center. your opponent - a worthy adversary (the GMAT), but no match for your skills.
not gonna lie, thats exactly what i was thinking as i got to the test center. complete with the "rocky" theme music and all.
