Passed 640-801 with an 885

I took the test a week ago and got a 847. This second test was harder than the first but still managed to pass it.

I used cisco press and sybex.

Oh and for all of you that have problems with prefix notation and dont want to memorize all of em I will give you a neat little chart I made to help me with it:
