Creating concept maps of the material or new acronyms to assist your memory can be fun and engaging. In college, you will undoubtedly have ample opportunities to do both. Think about your own preferences here. If you enjoy group projects, it helps to know when and how they tend to break down, for instance. Without a natural leader, groups can sputter and stall.
Groups can also waste a lot of time by socializing.
Consider assigning roles, for example. Let someone be the recorder and someone else the task master. If you prefer to work alone, you will certainly need to develop skills for working on teams. More and more instructors are incorporating small groups into their course designs and delivery. If you prefer to work in groups, you may have to develop more ability to work independently, for example, to conduct a library literature search or write a quality paper.
