Just thought of this from reading a another post on handwriting..I always used to join my handwriting and slowly it went is there any point in english language exams in joining your writing??
Joined up writing is taught to people because it is supposed to speed them up in writing. There is more effort put into teaching people with dyslexia a specific handwriting style to try to help them speed up in written work, for example, along with what is taught at primary schools. But if you are able to produce a fluid and quick script without joining then noone is going to penalise against you.
