What are you working on?

Once you’ve trained for a while, you start to gain a sense of what you need to work on. Maybe your footwork is flat. Maybe you do terribly against inside fighters. Maybe you only kick with your dominant side.
Now that you’ve identified an issue that needs work, what do you do? Work on it, obviously. This doesn’t mean you have to come up with drills on your own, and it doesn’t mean you only work on it during sparring (but those are both fabulous things to do), it means tell your coach what you’re thinking. Good coaches will listen to what you have to say and integrate it into the class. They’ll use your feedback to help you improve.
It doesn’t matter if your coach already knows the problem you’ve identified. It lets them know that you have taken charge of your training, that you care about your progress, and that you aren’t simply a passive vessel waiting to be filled.
Identify something you need to work on. Attack it until you make progress. Move on to something else you need to work on. Attack that. Repeat for the rest of your training career.
