It's okay, but you need to do some reading on your own. The process is complicated but there are a multitude of resources available online to help you with this. SDN is one, but before you post a new thread, try using the search function to find answers to your questions first. But actually, the best place for you to start would be the TMDSAS website itself. Here's the link:

Read through the topics on the left-hand side, read through the FAQ, and
afterwards, if you still have specific questions about certain details of the process, return here and ask them in the "Republic of Texas" or "TMDSAS questions" thread. Hope this helps.
