The navigational section and fire extinguisher section could be more extensive in order to properly retain and commit to memory. The final sections were purely common sense and I flew through them as I expect anyone else would. The final charge of $10 was confusing and took a lot of back button and time to search for a reason as to why additional payment is needed. Most people will assume the $34.95 in the beginning is the one and only payment. An explanation and better instructions to acquire the verification ID # would make it easier.
