Advice on how to approach preparing for C1
I took and passed B2 in November 2025 (well, I didn't know until March 2026). While I have been doing things here and there to maintain my level, I would like to continue my journey to C1. Because of a scheduling conflict, I cannot take C1 until May 2027 so I have plenty of time to prepare for C1. Also, this conflict might be a good thing because I bombed the audio comprehension (9.XX) of B2. Although I did horribly in the audio comprehension, I did fine in the other areas - reading (20.XX), writing (21.XX) and speaking (25). I guess what I'm looking for is any advice or recommendations for something like "pre-C1" prep (clearly, I have to work on audio comprehension). I fear that if I start studying for the C1 exam itself, I will run out of prep materials and/or become burned out by the time May 2027 rolls around. If anyone else has been in this situation (i.e., having 9+ months to prepare for C1), I love to hear what worked and what didn't work for you.
Thanks in advance.
