        Debug.Log(levelIndex); // Outputs 12

using UnityEngine.SceneManagement;
public class TestingScript : MonoBehaviour {

}
A new static class (not inheriting from monobehaviour) that holds information:
public static class StaticClass {
    public static string CrossSceneInformation { get; set; }
}
A script attached to a game object in scene "Test2":
using UnityEngine;
public class TestingScript2: MonoBehaviour {
    void Start (){
        Debug.Log(StaticClass.CrossSceneInformation);
    }
}
