Hello S3!
Here is your homework exercise on telecommunications. I would like you to put the answers to each of these questions in your blue homework jotter and hand it in to me no later than Tuesday 14th September. You will not receive credit for doing the homework if your jotter is handed in after this deadline.
Use the calendar on the right to check for any important dates (HW deadlines, assessments, parent evenings) during your Standard Grade course. There is a podcast button under the calendar that will help you to subscribe to all future hw and answers on iTunes. Just ask if you need help with that.
