If you have a documented functional disability (such as Dyslexia, ADHD etc.), we advise you to do the following:
When planning your English test, try to see if you can arrange to have extra time to take the test. For example if you take a language test at the Erasmus Language & Training Center, extra time can usually be granted. It may be more difficult to arrange this when taking a standardized test (IELTS, Cambridge or TOEFL).
If after taking the test your scores are insufficient, contact the RSM admissions office for further advise. If you already started your application, you can add your current scores, along with documentation about your disability (such as a dyslexia statement) to your application.
