			==Studying for Exams==
			Most exam questions will be based on coding similar to labs or coding having to deal with concepts that you've already covered in physics. One good way to prepare is to solve the problems with a set number of variables, then looking back and writing down the variables that change. Finally, create the objects and write the needed characteristics of these objects.
			The exam questions will not be perfectly similar to a lab or any previous question; however, if you practice coding outside of the lab, create other simulations, and understand how the basic syntax of VPython, things should turn out well.

	~~A typical~~ VPython ~~program has~~ the following ~~structure:~~		VPython reads linearly meaning that it reads down the lines as you type. Therefore, the following give you a good idea of how to begin your coding in terms for this class and physics in general.
	*~~Declare~~ all ~~the~~ constants that will ~~be used in~~ the ~~physical process you~~ are going to ~~model~~
	*Create all the objects that are taking part in the process		'''1. Copy the''' from__future import division / from visual import*
	*Start a while loop
	*Calculate the ~~forces on the given objects~~ (~~or any other factors that alter the position of the given objects~~)		'''2. Create and declare all variables.''' This includes any constants and any initial conditions. It's important to create your initial conditions before any loops.
	*Alter the ~~positions (or other~~ variables ~~you need to alter)~~ of ~~the given~~ objects ~~to observe their trajectory~~
	~~For example:~~		'''3. Create objects.''' In VPython, you are creating 3D objects that will most likely move. Characteristics of the objects are most likely going to be updated; therefore, they need to be initialized.

			'''4. Initialize a while loop.''' Once you have all your variables, write the condition of your while loop (condition being what you are working towards).

			'''5. Begin updating the necessary variables and characteristics of objects.''' This will include things such as velocity, force, momentum, object positions, and etc.
