Im lucky. I work shifts, but i have to be quite strict with myself on when i study. First thing i do is get MS Publisher going and create myself a study plan on the calender.Put all my shifts in, days off etc etc. On a day off i will do 14 hous of study, split into 3 chunks with breaks in between. I start at 8am and finish at 11pm with hour breaks. In the evening i wont get in from work until 7:30, so i dont start study until 9pm until midnight. Nightshift...forget it. Have a few hours when i get up to myself.
Im doing my study with Bristol. They break the study down into fairly well balanced Modules. Im doing 1 module a week at the moment, during which i'll make bullet points from the notes and do the progress tests. Tip- Read the worked answers for these. They sometimes make much more sense than the notes!
I will then re-read the notes following the modules again, and again do the progress tests. I will then re-read the bullet points, learning off by heart things such as the radio frequencies and wavelengths. I find repeated reading is the best way to learn it. The more you read it the more some things that you didn't understand suddenly 'click'. I then plan a revision timetable for the last 2 months again on Publisher. I work out how much study time i have over that 2 month period and break it down as i believe its requied i.e. Gen Nav maximum revision time, Coms least.
Don't worry too much about practice papers. When you do your brushup course they are non-stop from Alex, so just know your stuff prior to you getting there.
Module 1 is very calculations based, knowing formula, being able to work answers. Module 2 is more factual based, and being able to recall facts and figures. Personally im finding Mod 2 harder than Mod 1 but its horses for courses!
Lastly always give yourself a day off. You need it otherwise your brain will explode, and the wife starts asking for a divorce when you explain to her Schuler Tuning!!
