Test center problems...Advice needed URGENTLY!!!

[stars_ahead]

So I gave my SAT this last saturday.When we were on the 2nd section my teacher made a mistake in timing and called the section 5 minutes earlier. We then told her about it and she gave our 5 minutes to us separately. But her mistake stressed me out and I got really confused. I couldn't even calculate my time for myself. I was rushed and confused all through my test after that. So much so that in the end after I had completing my test I just strtd flipping through my book. My teacher saw that before I could realize it and said he would report me. So what should I do now? Should I report the teacher's mistake or should I wait for collegeboard to contact me regarding my test? Has anyone gone through a similar experience like that ...If yes then how did you handle the situation. Please advice. Your help is appreciated. Thanks.
