瑞典学校申请全过程记录
记一下我申请 🇸🇪 学校的流水账吧。 为什么要申请瑞典的学校？ 我其实最想去的还是德国，因为除了巴符州之外的学校不 要 学 费！瑞典的学校是挺不错（皇家理工、隆德、查尔姆斯理工等），但是针对非欧盟居民要收大约二十几万人民币的学费。另外就是，有条件申请全奖（大概就是学费豁免）的大佬应该也不会申这边吧。 反正申请学校就是要当「海王」，瑞典的当个「备胎」也挺好。申请程序比德国简单，申请费也不贵（900 瑞典克朗）。 如何申请 瑞典大学申请统一在 大学申请系统UA 上进行，所有文件都可以以 PDF 扫描件的形式上传系统。不过⚠️，**文件一旦上传，提交所有文件都会被所有学校的招生人员看到！**每个申请人最多申请四个项目，四个志愿是有先后顺序的： 申请人如果被申请列表上的某一项目录取的话，后面的志愿都会被删掉。 只能在第一志愿上申请奖学金。 关键日期和截止时间 以系统上的信息为准，2023 年硕士秋季入学的申请时间段是 2022 年 10 月 17 日至 2022 年 1 月 16 日。 我的申请 我申请了两个学校，皇家理工学院 KTH（瑞典语：Kungliga Te ...
