It will not be as easy to ask questions during the lecture. Your microphone will be muted most of the time. And, it not always be so easy to type in a question into the chat box. For this reason, I am planning to take a break, about 10 minutes, in the middle of the lecture. This will allow you to take a break if you need one, or to ask questions. If there aren't too many questions, I can unmute your microphone at that time. I will also hang out after the lecture for a few minutes to answer questions. Other than that, you will need to rely on email or the online time.
It will be a little tougher to get help on an exercise or an assignment. You will need to take advantage of extra online sessions and use email to ask questions. Usually, when you have a question about your code or an error message, I need to see your program. It is best if you email me your entire program (and not a screen image of part of your program) and make sure that it is clear that you are asking a question (put "Question" in the email subject). Usually, I assume you are submitting the code for grading.
The midterm and final will be open book, open notes, open computer, open compiler, open internet. And also, timed. Given enough time, you would be able to find the answers to all of the questions. But you won't have enough time. The assumption is that you are not going to have to look up everything - that you actually know most of the topics. The assumption is also that you are honest - that you will not be sharing answers, soliciting answers or having someone sitting beside you doing the test.
