al's Thoughts

Open Book/ Open Note - no electronic devices! Be very clear about what specific answers you are giving. No more than a dozen lines of code at a time. Some questions will be specific on the amount of code you can write. No multiple choice or true false. There will be lots of looking at code and saying what is wrong with it. Do the exit survey!!
