Timetable and enrolment issues

Hi there, 


I have accidentally enrolled in all classes in the first semester not knowing that it would only leave one for the second semester, thus causing clashes and an overcrowded timetable for the first semester. How can I change some classes from the first semester to the second? If I drop individual classes does it appear in enrolment for the second semester, not wanting to click drop in-case I cannot revert? 


Thanks for your help Smiley Happy
