Sorry, merlion mm, i still can't give any suggestions to anyone yet. but i truly understand what you meant by 心理紧张着呢. i think how you deal with the pressure is also an factor lead to success. A little bit of tension may help you focus on the study before the test, but don't be stressed. Sleep well. be confident!!!
One suggestion to avoid stress is really prepare for detail things, like clothing, transportation, and what if you make a mistake at first SC or what if you have two consecutive RC.....That wll give you confidence when facing different situations.
