This is a modified version of my CCNA solver from last year.
Since Cisco changed the whole test structure in the new V5.0, I had to change in the methodology of this script. Now it writes the correct answers after the question. You have to specify a chapter number in the last line of the code! There are 2 parameters for the main function: chapte…

| * Hi, this is a little code, that you can run on a Cisco CCNA test and it will answer every question for you. | |
| * Please, learn the lecture! | |
| * | |
| * I can't garantee anything! If you use this and you fail... Well, it's your falt. | |
| * Cisco used to change a bit in the texts of the questions, so I can't garantee that this code will even work after some weeks, but I hope ;) | |

| * To run it, just simply: | |

| * Chrome - Ctrl + Shift + i -> Console tab -> paste the whole code -> specify a chapter number in the last line -> Enter -> Don't shout! :) | |
| * Firefox - Ctrl + Shift + k -> paste the whole code -> specify a chapter number in the last line -> Enter | |
