I have finished two OGs, and start summarizing SC errors, that part is my weakness. After finishing two OGs, my understanding about the grammer notes given by XDF is better, I think I will conquer my weakness, because my correct rate in Supplemetary materials is higher than ever before. Thx a lot for this forum.
I have got an interview form PWC so that I prepared a whole week for that exam. And I will restart my diary today, And I have finished the Grammer Explanation by BaiYong. The result is much better than before.
