It may not work for you as you may have a different learning style but I would write out all the basic Procedures in my own plain English and then learn that. I find by cutting out all the extra information that the manual has and breaking it down to the actual actions I'll take ,makes it much clearer to me and easier to commit to memory.
I would do the same with the airports information I was going to jumpseat to, basic summary of procedures and frequencies etc.
I would work six on one off while on the break and those six would be three jump seating and three studying at a local library where it's nice and quiet.
Hope that helps.
