You can do screen shots as mentioned or a lot of copy/paste. After hours of doing this and only having week 1 material I quit and used my "higher score gaurantee". With Kaplan you can say you don't feel ready and get access to the course for another 4 months or so for free.
Keep in mind this does not save your scores. If you chose to do that I would still copy your FLs and quizess because they all reset.
