Always strapped, You are better off waiting until the forth and going to the office.
They will do electronic finger printing there and assist you with the application. If you fill it out yourself not only will it be a longer turn around time but for a lot of the fields you have to use specific codes or it will delay the application (Ex. Eye color has to be HZL for hazel).
I've been to the WPB office twice this year for my D and G licenses and had a decent turn around time and they are very friendly up there.
If you have any questions, I'm in the broward area and would be happy to help...
In the mean time, even though you had the class... This down time is a great time for you to print out the FS 790 and read through them a bunch more times. High light the important statutes so they stand out when you are looking something up. In my opinion the most important part of carrying is being familiar with the law.
