The CCNA exam will not change on June 2007 what will change is CISCO academy program structure, the material will still be the same but they will divide it into two levels one for beginner level and one for advance level.
If you finished all CCNA courses and you did your revision you only need to revise latest pass4sure and you will pass Inshaa Allah. The exam is not hard and generally more than 90% is from pass4sure. So if you can just review pass4sure before the exam do not delay it, you won't need anything else to pass the exam and get a good score Inshaa Allah. Best wishes
