You've got a lot of time so make sure you go through the syllabus point by point for each subject and make notes pertaining to each point. That's what I do and it ensures you cover everything you need to know. You could count the number of topics in each syllabus (Not all the bullet points, the main topics they are in) and then look at how many you think you could cover in a day. Your timetable should then be based on that.
