If you cannot supply proof of your proficiency in English at the time of application, you have to indicate which test or proof you will be submitting. For example, you can indicate that you expect to get grade 8 in English on your Dutch VWO diploma, or that you will be taking the TOEFL.
NB: AUC needs to receive the proof before you can be admitted. So if you are invited to study at AUC, you must still take the test/achieve the grade! You must be able to submit the proof to AUC by 15 July for a September start.
Please note that AUC expects students to meet the admissions requirements in the way in which they indicated on their application. Any changes must be requested in writing in advance, so that the Admissions Committee can decide if they accept the alternative proof.
For example, if you say on your application you will take the TOEFL, but then achieve a very high grade in English on your secondary school diploma, you cannot simply cancel your TOEFL and submit your secondary school diploma instead. You must first check with the Admissions Committee that the alternative proof will be accepted.
