Judge told me it's 11 points to lose my license no matter what age. now I'm suppose to hand in my license because of his mistake

I got a speeding ticket but it was dismissed a month later i received a rewritten ticket for the same violation. I fought it because i was confused why it was reissued. I went to court & was told it went to the wrong court that why it was dismissed but that the officer could rewrite it. I fought the ticket because i have 4 prior points and can't afford to lose my license because at the time of the stop i was under 18. I tried to tell the judge multiple times that my understanding was if you reach 6 points under 18 you lose your license. He reassured me multiple times it is 11 points no matter how old you are. So i settled for a lesser ticket of 6mph over and 2 points thinking it wouldnt matter. I"m now 18 & have 6 points on my license and a letter from penndot saying to turn in my license
