Asking for Advice

I'm part time self-study F3 without having any class and plan to sit for the paper before Jun'15. But I'm not very confidence with the study materials that I having now. I had the F3 text book and revision kit for 2014 and also had downloaded the course note and pilot paper which is for 2014. So may I know is these materials enough for me to prepare for the Jun'15 exam? Thanks!
