between instructor and instructor Id Make them both instuctorid
there are a lot of those like group code could be groupid and unit title should be an unitid to unitid
you might consider day to have 2 fields for a start and end date every Monday between 1/1/2013 and 1/3/2013 or a semester table so you don't have to put the date in every record just the semesterid
