Partition is this the best way?

Assume disk exists + no partitions already exist

fdisk /dev/sdb

select n + p as before

Partition number (1-4, default 1):
Using default value 1
First sector (2048-41943039, default 2048):
Using default value 2048
Last sector, +sectors or +size{K,M,G} (2048-41943039, default 41943039): 1000000

For second partition:
use default value 1000001
for last sector, 20000000

For third partition
use defaults

Check with fdisk -l

Device Boot Start End Blocks Id System
/dev/sdb1 2048 1000000 498976+ 83 Linux
/dev/sdb2 1000001 20000000 9500000 83 Linux
/dev/sdb3 20000001 41943039 10971519+ 83 Linux

Write file systems to each
mke2fs /dev/sdb1
mke2fs /dev/sdb2
mke2fs /dev/sdb3

make mount points e.g. p1, p2 + p3 in /media

Configure fstab as follows:
/dev/sdb1 /media/p1 ext2 defaults 0 0
/dev/sdb2 /media/p2 ext2 defaults 0 0
/dev/sdb3 /media/p3 ext2 defaults 0 0

Try mounting

Place an executable in p1
un mount p1 e.g. umount p1
Change fstab record (p1) to ro
mount p1
try write to p1 (shouldn't work)
create link ln -s /media/p1/exercise /media/p2/exLink

If you havent created partitions before, use a GUI like gparted or the KDE partition manager.
It gives you a visual cross-section of you disk and you can create new partitions, resize, format to particular filesystem types, change sizes if you are not happy, label (name) them...and all before you hit the "apply" button.

Moving partitions is a bugger...takes forever...dont do that

Partition is this the best way?

In the absence of any information on what it is that you're trying to achieve, I'd have to say that, if you've achieved your objective, then your way is good enough.

Is it the best way? That depends on what your criteria are for measuring the "best-ness" of it. Quickest? Easiest? Other?

If you shrink the partition so there is no free space, move it and then expand it, it takes a lot less time.
