I'm not going to sugarcoat it: I failed Cambridge B2 First twice before I finally passed last March with a 172. Both times I went in thinking my general English was good enough, and both times I got absolutely destroyed by the Use of English paper. I genuinely didn't understand why until I started working through a proper FCE practice test and realized I was skimming questions instead of reading them properly — especially the key word transformations.
What changed everything was finding a structured FCE study guide that broke down each paper individually rather than treating the exam as one big block. I spent six weeks focusing almost exclusively on Reading and Use of English, probably 90 minutes a day. For Writing I forced myself to write at least three essays a week under timed conditions. The difference was embarrassing — my Part 1 essays went from C grade to solid B just from practicing the structure.
For anyone else preparing, what's your weakest paper? And has anyone found good resources for the Listening section specifically? That's the one I still feel shaky on even after passing.
