Learn how much sleep your body needs and plan your schedule accordingly. It is a good idea to get regular exercise, maybe 10 minutes per hour of studying. Healthy foods are essential to maintaining a healthy body. Seek to understand the concepts in the courses you are taking. Don't be lazy in working problems.
Engineering students learn important concepts by working problems.
Sometimes you will study alone and sometimes in a group. A quiet place is most effective. Do your homework as it is assigned, and complete reports on or before the due date so you have time to proofread. An assignment book or sheet is helpful. When taking tests, learn to pace yourself so that you can use the allotted time wisely.
