Hi Shellie. There is very little difference between the 7.3 and the 7.4 exam. If you have experience on 7.3, that is fine.
With the 4 day course under your belt and your experience, you are in a good position. If you've seen the sample questions, then you are familiar with our certification site. Grab the pdf version of the exam content guide and look over the expanded list of topics. Practice any areas that you are not familiar with. Here is a link to the content guide, click on the pdf download.
