1- download using torrent the CBT nuggets videos on ICND1/CCENT exam (for ccna1 and ccna2)
2- download packet tracer, watch some video tutorials on how to use it.
3- do some exercises on packet tracer.
4- download some ebook and study from it, exam cram books are good as quick guide.
5- you can also check professor messer videos on network+ certificate, it overlap a lot with CCENT
I had my CCNA certification 2 years ago.. and i fully agree with m_zeid... Please don't forget to practice a lot on the packet tracer.
