Remember some points abt GMAT
1) It is not a competition
2) GMAT scores are not the only deciding factor
3) GMAT doesnt test you history or geography so it is more about skills and common sense
If you keep the above in mind, you can go to the exam hall a bit more cool than sweating out to reach the 700+ figure
