how much actually gonna cost me if i taking CCNA tests including classes?

it is a little pricy..but u get 2 experience the real thngy instead of only watching books rite? do u thnk its a gud idea 2 take CCNA if need 2 change field, means frm non-IT field 2 IT field.. interested in networking thngy.. enter wrong job liao last time..

i'm not actually know where i belong.. i know PC, i can buka my pc n put it back.. my house is wireless networked, with 2~3pcs..port forwarding/IP detect/ez network prob shouldn't be a prob 2 me.. my office router network/pc prob also find me.. but i only studied pc back in high school..

thnk d point is not d material who make ppl dump, only ppl making themself dump? cant entirely blame 2 material, it only tells u watever it writes on d material, somethngy cannot entirely tought by books n all, so on hand experience is also important.

as i c, reading ebook u need 2 stick 2 ur chair n table, while real books u can take here take there, adjust abit d way u sit..more flexible sometimes..

i wonder wat does it mean by valid 4 3yrs? u mean after 3yrs d cert is totally rubbish n u need 2 take a new 1? hmm.. tat doesnt sound gud..

which mean every 3 yrs we need 2 retake a 642-xxx exam in order 2 maintain d certification?
