How to tell when transform rotated 360 degrees

I want to give a score if the player rotates 360 degrees from its current rotation position. I want a full spin.

Here is the code:

 public class SpinScore : MonoBehaviour
 {
     float currentZRotation;
     
     void Update()
     {
         currentZRotation = UnityEditor.TransformUtils.GetInspectorRotation(gameObject.transform).z;
 
         Debug.Log("z rotation: " + currentZRotation);
         if(currentZRotation >= 360 || currentZRotation <= -360)
         {
             Debug.Log("You spinned");
         }   
     }
 }
