CA(transfer)推荐系统里 并没有将pdf上传，只是将内容copy放在最后一个问题里

今年申transfer，老师转发邮件给我，中介帮我填的链接。那个CA的推荐人系统里说上传pdf不是必须的，只要回答前面的问题就行了。最后一个问题是: Please write whatever you think is important about this student, including a description of academic and personal characteristics, as demonstrated in your classroom and/or the campus community. We welcome information that will help us to differentiate this student from others. (Feel free to attach an additional sheet or another reference you may have prepared on behalf of this student.) 中介直接把之前准备好的pdf复制上去了，最后就没有传pdf。虽然我有mail我所有的纸质版带学校抬头和老师签字的推荐信到所有申请的学校，我担心是不是这样直接文本输入而不是上传pdf的方式会影响材料审核人对我的印象？因为我看到地里的一篇帖子里写着”文本输入“而不是pdf会被定义为”黑推“。
