If your second turn was timed well, you should finish a reasonable distance from the kerb. If your wheels are more than around half a metre from the kerb, you should move forward or back (whichever is easiest) to adjust the position. Take your time. Remember to use the POM routine and take effective observations each time you move.
Avoid mounting the kerb, but don't worry if a wheel touches it lightly. Just change direction and move slowly away from the kerb, until you have enough room to correct your course and straighten up.
When finished, engage the handbrake and select neutral.
