MattyGmon1,
First - it has been a long time - after 4 years unless you are working with the stuff daily - you will have forgot a TON !!!
Also - try not to "piggy-back" on another post - start your own
1)Read Sybex CCNA Study Guide 2x front to back
2)Get 3 Cisco 2501/2503/2514 routers from eBay with 16 DRAM and 16 FLASH and practice EVERYTHING you read about in the book.
It would help to have a switch or 2 but they are not cheap - you might have to find a good SIM for those - Boson has a very good sim - they should have a FREE demo at
3) You said you completed the Cisco Academy - did you join the Academy alumni site when done - if so go to the site and get tools like the free SIM - Packet Tracer to work with as well as reviewing the online content.
If you did not you will need to contact the Academy you were at and see if they can help you get back in - most students just do not get all the extras that Cisco provides to the Academy and alumni of the academy.
4) Look over the prior posts here for lots of good info and links to free stuff on the CCNA.
Good luck but without more on your background and what you have been doing with networking over the past 4 years - best I can do!!
Good luck
