When in computer science class be cool!!
-Remember you are the coolest in your year for selecting this class
When you come into class don’t log in until told
Always remember your coding/theory book
Don’t distract others when they are practicing their coding-You need to
concentrate!They also need to concentrate!
Please sit in the seating plan which you have been told-ie Boy /Girl
Don’t distract your wonderful teacher during classtime!
Don’t play games –unless it is one you have designed!
Complete your work you are set
Complete your homework
Don’t be afraid to get coding wrong
Don’t feel intimidated by computing terminology
Write up your notes as you go along so that you have revision notes
Remember
If you are finding this tough it is normal
It is a very tough option and some of you may
not stay the course
You will need to concentrate and let others
concentrate
Before we start
Please look at the guide document for accessing online
resources for computer science.
Please don’t lose this.
Today we are going to start theory for a451
I need you to write your name on your book and my
name
Your theory notes go in front of your exercise book.
You must bring your exercise book with you each lesson
As I run through the overview powerpoint you will need
to make notes
