1. The forms that your instructor will hand out requiring a notary signature, are exactly the same as DPS will send you. Use the one's instructor hands out(assuming you haven't received the DPS application packet at time of class)If I'm understanding this correctly, I can still TAKE THE CLASS, but I cannot use the forms that the instructor provides. I have NO IDEA what these forms are exactly that I cannot use (instead having to use the DPS forms in the packet that I have not received yet). The class I signed up for lists that they include "all forms, affidavits, notary, fingerprinting, and photos".
2. Of course you will have to use the photos they take in class. Regarding the fingerprint cards: use those as well. You have to(if you haven't received the DPS packet). That won't be a problem at all.
In fact you can use just about everything the instructor hands out EXCEPT the page(s) about personal information(name address, work history, criminal history, etc etc). THAT will already have been done for you by DPS when you applied online. [it's 5 pages btw, when you receive the DPS packet]
Sorry if I confused you. Please note the info on the link you posted from TCHA made statements I believe to be incorrect, as all of the forms & affidavits are identical EXCEPT the personal information pages.
With all that said, when in doubt ASK! Ask here, and if there's still some doubt call DPS. They are friendly and helpful. Explain your situation. I know I did before I took the class. I called down there at least 4 times that I can remember, AND asked dozens of questions here.
I'd be happy to list everything that I received from DPS in my application packet if you think it'd be of any benefit to you. I have copies of every scrap of paper I received in the application and class process. Even my qualification target!
