You may reapply using the "I do not have a school-issued email" drop-down option to attach supplementary proof of academic affiliation (e.g. a schoolool card, transcript, or affiliation/enrollment verification letter.) Make sure your supplementary proof is official and dated.

問題：
1。 using the "I do not have a school-issued email" drop-down option
請問這個drop-down option在哪裡？
2。我需要上傳school ID card，沒有地方讓我傳。

Answer 1

我記得好像需要使用edu信箱。

Answer 2

同學，他是讓你在驗證學術狀態的下拉菜單中選擇"I do not have a school-issued email"，然後就會出現一個可以上傳證件照片的控件，這樣你就可以上傳了。對了，順便說一下我之前是用學校的在校證明驗證成功的，學生證應該也可以。

Answer 3

優惠？難道這破網站收費？ ？
