If you would like to register a different recommender you will need to first exclude the original entry before you will be able to add a new one. To do this, click on the name of the teacher you currently have registered on your Recommendation page, and then click "Exclude" at the bottom of the dialogue box. That entry will then become inactive and you will be able to register a new recommender. If the original recommendation was previously submitted, it will not be included with your application, so please only exclude recommendations you no longer want to have considered.
If you registered a recommender with an incorrect e-mail address, you can follow the instructions above to exclude the incorrect entry and register your recommender again, or you can contact us directly with the correct information and we can update it for you.
