What if I complete my real estate courses early?

Right now I am 8% done with my first real estate course to get my salesperson license. Right now I am on pace to finish in under the 45 hours. My question is what will happen if I complete my course in let's say, 35 hours? Will I have to sit in the class for another 10 hours? Or does it really matter? 

Also is it normal to be ahead of schedule when it comes to taking these courses? How long did it take you guys to do your courses? I am doing my courses through Real Estate Express and it seems to be a good program.

Thanks for any helpful info!
