First, make sure that you filled in the TOEFL test date wrong when filling in the online application.
Supposedly, your problem is not big.
Because even if the online application is filled in incorrectly, ETS will not make mistakes if you let ETS deliver it.
This is why the school only recognizes the delivery of ETS as an official achievement.
And your own score in the online application will not be referenced.
Not to mention the exam time.
If you confirm that the information is correct, what you need to do immediately is to call Purdue directly:
1, indicating your name and online account number and other information to prove your application identity.
2. Explain to the school that there is a problem with the TOEFL test time on the online application system, and ask whether the TOEFL score school has received the official score sent by ETS.
3. Explain that the final notice has not been received. I want to confirm the application result.
Send an email while making a phone call. E-mail may not be answered in time. So making a phone call is the fastest.
Good luck!
