This unit was the hardest one so far. My muddiest point are the circular permutation and the binomial questions. Sometimes i confuse when to use pick and choose formula. I didn't do the scribe post yet, cause I don't get those binomial questions. :(
Zhū Shìjié 's Chinese name is 朱世杰. Hope we do good on the test!
