Do I have to take defensive driving when on deferred disposition?

I got a speeding ticket and then got another ticket the following week, so I got deferred disposition for the second ticket. However, the judge did not make me take defensive driving as part of my probation, but ive read that under texas law if you're under 25 you have to take defensive driving for deferred disposition. Now I don't know what to do! because I'm 23!!
