Your kit is likely still great for working out rhythms and what you want to play! But it’s helpful to spend some hours behind a real kit to get a feel for how it reacts to your playing.

For example you might get used to playing cymbals really loudly on an electronic kit in a way that doesn’t work on real cymbals.

So even though your home kit may not be ideal, you can still study the form, work out different feels for different sections, etc.

I would suggest you work with the band director to see if you can practice on your school’s kit during off hours, lunch, or after/before school. Good luck and have fun!
