Cambridge Certificate (CPE) practice material

[keiki]

Hi everyone! I just registered for the Cambridge Certificate of Proficiency in English (CPE) exam in June. Since there is no preparation course in my area, I will have to practice on my own. I finished school last year and university won't begin until autumn, so I have plenty of time. I just ordered "Objective Proficiency" and I was wondering if any of you have taken the exam too and could tell me something about it. Is there any practice material that you can recommend? Anything super important to practice?

Thanks in advance!
