thank you
You do not need to apply again. Your academic referrer ID is valid for as long as you wish. What expires is the evalution key, so you need to ask for a new evaluation key every 6 months. If your new students enter your referrer ID (which is your last name), they will get a fresh new evaluation key.
Feel free to use the following academic key: 4BH-VAY-AZG-ZM7-TMP
