You've been a member for 8 years and finally decided to go for it, so I'm sure that you're sure that this is the right decision. Hopefully it won't take you 8 years to decide which field to go into. I'd go with FE or Med Supps. Just choose one and jump into it! FE's probably the easiest to start with.
Congrats on passing your test and best of luck to you.
I though I was bad with a 5 year wait.
