Building on the success of Catch Up Chemistry and Catch Up Maths & Stats, this title is an invaluable primer for any student wishing to get up to speed with the biology required for their degree. The book takes a hierarchical approach, starting with an introduction to the molecules of life, moving on to consider cells and their functions, how cells are assembled into tissues and ultimately the various systems of the body. Biology is a huge subject so this text selects material that will be most useful to students studying courses related to medicine and the medical sciences.
