I have completed 3 semesters of CCNA (2.1.4) Academy and I am on my 4th semester (3.0). <--- this is what has totally thrown me off course. they changed the curriculum on my last semester at the academy. it is different. I plan to take the CCNA based on the old curriculum because I was preparing in that one. I even bought the Boson 640-607router tests to make sure I am on track. what are my chances with all this of passing the CCNA? will aceing the router tests do it or do I need to go chapter by chapter on the old curriculum?I mean I am nervous because of the changes.
