Hi! I am brand new to the Arduino community and Arduino component as a whole. I was wondering if someone could help me read this schematic and also see what I am doing wrong for my Continuous Rotation Servo exercise. I am trying to finish this by tomorrow so hopefully I could get insight on what to read and what to fix/avoid.
First thing, that diagram shows you putting 9V into the 5V output pin of the Arduino. If that's real life, the result is one very dead Arduino. And if that USB cable is inserted and hooked up to something on the other end, quite possibly a very dead something as well.

You need to have a word with whoever drew that, as it leaves quite a bit up to the person to interpret.
Schematics must be clear and complete. A bit like source code - with comments to annotate details.
Arduinos are quite forgiving...
May still work.
But remove connection to 5V!
@aquassense : what does your sketch do? Does it output anything to Serial?
By the way: the vex voltage is labelled 7.4V, and connected to 9V...
Maybe the VEX is ok with that, but you did not add any links to that controller...
Also a 9V battery like that will be able to turn a small motor, but it will be very weak to drive a car.
In order to read a schematic you have to have a real schematic to read. As others have said you have not got a "proper one" so explaining it is impossible.
