Well DPS has come along way, they now have everything online, so now you can go to their website. Click the apply as new applicant , answer the questions, and pay for your license!
There is no real way you have to do it. You can pay before you take your class, or after you take the class. Just know this…..they are not going to do a thing until you pay the state for the license!
You just want to pay for the license before you sent your required documents to DPS.
