General tips that apply to all levels

📺 Watch YouTube videos of songs at the level you're trying to achieve. Practice reading the charts.
🎵 Play all of the songs of the level you’re stuck at, even the songs you don’t like.
📸 Take pictures of your accomplishments. We, humans, are naturally negative, especially towards ourselves. Taking a picture of your good scores will give you the feeling of progress instead of focusing on your bad scores.
🦶 Try optimizing and minimizing your footwork. Try to keep your feet closer together and use your heels for the blue arrows and your toes for the red arrows (heel-toe).
🥅 Have goals every time you go to the arcade. Write down songs you want to pass or songs you want to get a better score on.
