640-607 is open for students untill 31. I am very sceptical about taking it though since i've heard that its not valid as much as the 801. Supposing i take the 607, do i wait for three years before renewing it just like 801? As far as i can see the only logic behind taking 607 would be the assumption that it is easier than 801, which i highly doubt. Finally, cisco claims that if you have been prepared for 601 you can take the 801 and succeed.

Any suggestions are welcome and good luck to you all who are preparing for "TechExams".
