Hi @virtoix,
If you are new to memorizing, then check out the Resources page here;
As for preparing for your exam, 100 pages over 12 months are possible and should be enough time for you, but depends on what each page contains. So if each page contains a lot of info you need to memorise, then you have a lot of work to do.
Have a look at this link below which may give you some creative ideas to structure your plan.
