As far part 2 is concern, Once you get the assignment, I will recommend read the assignment couple of times and note your doubts and use this forum (make sure you don't post anything directly related to the assignment here). But general questions you can ask here.
Once you are done with Part 2, give part 3 online and then submit the assignment.
All the best !!!
