Planning for Net+

MrXpert

Hello!

My Net+ is expiring this year and i've taken the opportunity to start studying towards it. When I did the exam 3 years ago this was the 004 and I understand there's been quite a lot of updating since then including performance based questions.
I know I'm a CCNP but I like keeping everything up-to-date and am not going to underestimate the Net+ exam as want to score as high as possible and take it all very seriously.

I've been watching keith Barker's CBT nuggets Net+ series and am amazed at how much detail he goes into. It is far more indepth (for net+)than what I studied 3 years ago. Has the network+ changed so much in the last 3 years? is this material par for the course?

Can anyone tell me more about these performance based questions?
can you still go back and review your answers before submitting it finally?

thanks
