Long time Hollywood talent and producer Marc Summers at the NBS- AERho 2014 convention said: “I don’t get up on any morning concerned with whether or not you have a job – your plans and future are up to you” News Director at NBS Regional meeting reminded students “We all have lives too” Long time Hollywood talent and producer Marc Summers at the NBS- AERho 2014 convention said: “I don’t get up on any morning concerned with whether or not you have a job – your plans and future are up to you” News Director at NBS Regional meeting reminded students “We all have lives too” 12/25/20154

5 And remember What we cover here is to supplement your reading and studying of material If you just come to class you probably won’t learn much. If you’re not making an active effort to learn, you probably won’t learn much. Exam Tuesday – ‘can you carry on a conversation about what we have covered?’ What we cover here is to supplement your reading and studying of material If you just come to class you probably won’t learn much.
