Record succinctly the main points of the lecture. Do not take copious notes to the point that you no longer grasp the important concepts. After each class, review your notes, read the text carefully, and record any areas of confusion so you may use the question and answer portion of lecture or recitation. Use instructors on a timely basis - do not wait until just before the test to go in for help. The instructors want you to succeed and will work with you given the time to do so.
Biology is the science which addresses questions about life, both past and present.
It examines the origin, history, physical characteristics, life processes, behaviors, etc. of plants and animals. The study of biology involves the recognition of certain themes which unify this multifaceted science. In biology, we describe life by what living things do, abiding by the laws of chemistry and physics. Because of this, biology is a multidisciplinary science, requiring knowledge of chemistry, physics and mathematics. The lowest level of structure capable of performing all the activities of life is the cell.
