epfl可以提交AP的推荐信吗

我是转专业，申请项目相关的课题是跟着当AP的老师做的，但是epfl官网要求的是professor，听说欧洲那边对AP和professor区分比较严格，可以用AP老师的推荐信吗？还是说找不同方向的professor写信呢？

AP 不算 prof 么.. 还是说只能 full professor? 不过这种问题可以发邮件问小秘吧..

We recommend you to contact at least 2 of your former professors and ask them to prepare the recommendation letters.
You may provide a letter from your current/ former employer or other type of professor, but it might give less value to your application.
However, the decision lies in the hands of the Master’s admission board, who will review your whole application file in order to decide whether you can be admitted to EPFL. Therefore, we are unable to give you more information on the assessment procedure and decision criteria.   



. From 1point 3acres bbs是这样回信的，AP就give less value，不知道怎么选了_(:з」∠)_
