On the last day of 2015 I acquired the title of Cisco Certified Network Associate.
To obtain enough knowledge for the exams, I exercised almost every packet tracer activity and lab you can find in the online CCNA course. The importance of doing this just can not be emphasized enough. If you skip these, you might as well not take the exam at all. Also, a good idea is to buy the hardware if you want to practice at home.
You can find my course summaries, packet tracer activities and more on: my google drive

Because the CCNA course has a huge amount of abbreviations and terms, I made a short list of them, along with the description.
Thanks to Stijn V for the integration of the CSV!
