Wish Me Luck on IELTS

hahaha

good night.
tonight was the last meeting of my IELTS course in REAL English. it happened to be a final test, to measure what we students have learnt during the course period. it is just like an IELTS simulation exam. the test consists of listening, reading, writing, and speaking. yeah, we all know that. but this night, we just do the listening sect 3 and 4, speaking, and writing. as reading and listening sect 1 and 2 have been done during the progress test some time ago.
by the way I am taking the official IELTS on November 5, which means about three weeks from now. the test will be held in UKDW. I need band score of 6.0 at least. it will be used to enroll a master's program abroad.
wish me luck.
