Write a some more (in other words lot) of code ...........
Just reading RHE will not help. Best way of learning is
to write code. Now that you are on the ranch, take code
from the postings and verify it, then participate in
discussions.
Read each post, write your code to verify what is said
and then post your views. There is nothing wrong in your
approach, just that its not sufficient. I would say you are already half (if not more) thru to the exam ...
