From B2 to C1
Hey everyone! I have a question. I completed my B2 exams (results r not out but ig I've passed) and I want to continue to C1. My tutor has started a new job and can't have classes with me anymore, so I'm probably on my own rn. It's the last year of high school so that means I don't have much free time but I want to show progress even if that means slowly. My goal is not to sit for the C1 exams this year, it's practically impossible even with more free time, but next year when things will be less tight, I may be able to do it.
The thing is I don't know where to start from. I don't wanna go directly to sample tests cause I know my vocabulary is insufficient. Should I buy a textbook with like C1 level texts, exercises, maybe extra grammar rules, etc. and if so which do you recommend? After the book, I'll probably be able to move on to the DELE C1 sample exams.
As for Speaking and Writing, the two parts that are produccion, not comprension, do you have any tips on how to correspond to the level. My production skills are good but not perfect even in B2. What's the different thing they expect in C1?
For advanced learners, what is one thing you noticed that is different from B2 to C1? What is expected in that level and how hard it is in comparison to the intermediate one? I honestly feel stuck so I would appreciate it if someone could answer my questions.
Thank youu
