 External and internal structure of human heart (Figure 24.1 and 24.2 UEC pg 259 and pg 260)
 Urinary system of human (Figure 25.1 UEC pg 270)
 Structure of Kidney (Figure 25.2 UEC pg 271)


This list of exam tips is quite exhaustive. Use it as a check list to ensure all needed knowledge are in your grey matter before you set foot into the exam room. Though the list looks long and a bit intimidating, it is actually quite basic. If you know most of what is in this list, you sure get flying colours on your science exam.
