How to overcome difficulties
1. Slow down the piece to half its original speed and play with a metronome
2. Gradually increase the speed to practice with until it's back at original speed
3. Practice scales with different types of articulation like staccato to emphasise the first beat of each bar
4. Record and submit a video of yourself playing the piece to your teacher to read feedback
5. Play the piece in front of your class to see which areas you make mistakes on when playing with more nerves and pressure
