You have an option to review answers to the marked questions at the end of the exam. Also, navigating from one question to another using Back and Next buttons is usually time-consuming.

Access modifiers control the accessibility of a class or an interface, including its members (methods and variables), by other classes and interfaces within the same or separate packages. By using the appropriate access modifiers, you can limit access to your class or interface, and its members. Access modifiers can be applied to classes, interfaces, and their members (instance and class variables and methods). Local variables and method parameters can’t be defined using access modifiers. An attempt to do so will prevent the code from compiling.
