Thank you very much for replying and I realize that there are a lot of problems in my CV. I still have some additional questions.

1. The scores and GPA shown on the transcript and ranking certificate of my university are 100-points system. Should I convert it to 4.0-points system?

2. As for “The preparation and characterization of DNA fluorescent silver nanocluster”, I do not understand why it is wordy. Should I delete the first word “the”?

3. In terms of “Supervised by Researcher XXX”, is “Researcher” the incorrect connotation? If yes, how can I translate his title “研究员”?
