the most useful skill to me is english. I need take more time and energy focus on it,
whatever papers, presentations or group work. all of them need good communication skill.
I should use more valid sentences and words. need more check and feedback.
1/8 time has been passed, the time really go fast. To summary what I have got, it is really have many things to talk.
next step is more communicates and e-mails…
