Emphasise speaking.

We tend to focus on reading, oral understanding & writing. Those fit easily into "sit down and study for 45m" format. Speaking doesn't, and can feel uncomfortable or contrived in classroom settings. One of the big reasons "immersion" often leads to fast breakthroughs is because it comes with a lot of natural speaking. That's often the bottleneck.

You don't stop and think of the correct grammar, words or whatnot when speaking. You just try to make yourself understood as best as you can, with whatever language skills you have. Even 200 words is something. Engaging that intuitive improvisation can be really helpful.
