I have developed a small survey application in Django 1.6.2 which requires that the participants fill out a number of questions over 27 pages using a SessionWizardView

Overview

The most unique feature of the application is that it allows the user to rate a selection of 9 images selected at random in isolation. The user then has to verify the rating they gave each image when they are re-shown them in groups of three.

At the beginning I have two instruction image rating tasks where I make it clear to the user what they have to do and two "Spike" questions to make sure that they are paying attention. Lastly I have two pages where all 9 images are shown again and they have to select their favorite and worst

I implemented this using a get_context_data method of a SessionWizardView. Also included is my done method.

I previously posted a question about my models.py and there seems to be very few issues. I have also posted about my forms.py and am awaiting feedback. Its almost 400 lines of code (with logging comments so you might know what I was trying to do) but I thought it best to post it all.

I am completely self thought and have never programed before and am just looking for feedback on how to improve my application. There is a lot of very obvious stuff I have no idea of. Any help is much appreciated
