The preparatory course for studying at Jiaotong University is still good. Food, clothing, housing and transportation are all on the campus of Jiaotong University, and the management is very strict. Moreover, from previous sessions, it can be seen that all the applicants are from the top 100 of the United States, and the top 50 accounts for 30%. I'm not hiding it. I'm a student of Jiaotong University, but I'm not used to what this man upstairs said here. Can I get a certificate for the preparatory course? Don't work in an intermediary if you can't read. You are not only ignorant, but also misleading other people's students for your own benefit. What a shame! ! Don't worry, regular universities dare not joke about their social status and reputation (think about it, universities will ruin their reputation because of your tens of thousands of dollars), and some black-hearted intermediaries can mislead students by any means, boring, ignorant, worthless and shameless. You can go to Baidu, or ask professionals, and you will know how shameless they are. You can ask me again if you don't understand.
