Congrats, a pass is a pass and that's what matters.
I haven't gone very deep into the ICND book yet myself, what do you mean by block sizes if you don't mind me asking?

You may be looking down at the teeth marks in your backside but when it comes to renewal in 3 years time you will slaughter it.

block sizes basically determine how you find your subnets for a given subnet mask,

for example:

a /30 is 6 bits on 2 bits off, ( 11111111.11111111.11111111.11111100)

that is 252, you take 252-256 which gives you as block size of 4

so your subnets would be 0,4,8,12,16 etc.....

or 240 -256 gives you a block size of 16

so your subnets would be 0,16,32,48,etc...
the lammle book explains it all

it really helps you on determining wildcard mask ranges too!

watch your time on this exam icnd'ers
