Try to fill your life with as much Deutsch as you can, it helps a lot to watch German TV or listen to German radio. There are a lot of international artists for interviews for examples. They often interview in English before translating to German for the local audience. It’s great to know what the interviewer will say to practice!
You can also watch « Berlin Tag und Nacht » to catch on the local accents and expressions while not feeling guilty about watching reality TV. 😉
