If you made below a 73, do it. You have nothing to lose and plenty to gain. So give it a shot if you can find the time to study neuro. I'll be available for questions that you may have, and will post the answers to any interesting questions here. I will have office hours, but don't know when yet.
Appointments are possible.
What I won't do is lecture you. Did that already. The main thing that I think needs to be done is for you to fully answer the discussion questions yourself. But when stuck or totally confused, feel free to ask me for help. These were fine questions, and we covered this material, but due to the blizzard and the dead server, I forgot to add the discussion questions that these came from.
