分别是：三年全日制学位、四年三明治学位
三明治学位的解释：Sandwich degree courses are courses which incorporate an extra year of work experience taken between the 2nd and 3rd years of full time study. During this extra year the student will usually go on work experience in an organisation or department in their area of study.
应该是三年全日制当中第二到第三年之间参加其它社会活动一年，然后加起来四年吧，希望采纳，谢谢
