Notes for the student :
- [...]我选择了格勒诺布尔大学作为我的[...] : you must specify which university, otherwise it is very confusing. I advise you change the sentence like this "在仔细斟酌和大量查阅资料后，我选择了在格勒诺布尔留学，最终选择这所学校的原因有三个："
- "我在大学读的专业是国际经济与贸易，但在选择未来硕士阶段要学的专业时，我希望选择“经济管理类”相关专业。" : using the word "但" is quite unapropriate, it makes me feel like there is an opposition between what you have studied and what you want to study in France. In my translation, I'll use a better way to express it.
