Here's what worked for me:
Stage 1
Read through each frame and just try to understand everything.
Read through again, and try to memorise any facts or formulas. Making notes and drawing diagrams can help here.
Take the progress test, without referring to the notes, and have it marked.
Review the marked answers, including the questions you got right.
Move on to the next frame.
Stage 2
When all subjects finished (and you think you remember nothing of them) hit the online question bank.
Create a huge test of the questions on one subject and start plugging away, an hour at a time.
If a question comes up and you have to guess it or you get it wrong, write the question number down (creating a list in word like 123,124,126.. will help later).
If you get a second question wrong on any topic, re-read the notes on that topic before carrying on. Ask online about anything you can't understand.
When the test is finished (it may take several days), create a second test of all the questions you got wrong the previous time (you can cut and paste that word list from earlier). It's likely to be at least a third of the size of the first, so may take a couple of days to get through.
If a question comes up and you have to guess it or you get it wrong, write the question number down etc etc
Repeat the whole process, creating shorter and shorter tests, until you are getting few questions wrong.
Stage 3
Attend the brush up.
The tutors will go through the entire syallabus again and give you questions to do each evening. By now you will be familiar with the style of questions and the areas of interest to the examiner. You will feel confident.
Stage 4
Take and pass the exams.
Drink Beer.
